TEXT: The author examines the pure bending of girders with an axial
row of rectangular cutouts in function of the influence of this
row of cu.
outs on the distribution of stresses and the ability of
distortions of the
girder. Special attention is given to the influence of the row of
cutouts
on the distribution of theuiitary stresses in front of the webs.
In a fu-
ture paper, he will present the investigations on bending with
cutting folas
The experimental studies have been carried out by the
photo-elastic method
in the laboratories of the INCERC (Institutul de cereetsri pentru
conalrue-
tii Ti. economia construcliilor Research Institute for
Constructions and
Economy of Constructions) in Bucharest. Models, having some
characteristics
have been studied. cXH is the-height of the cutout, in which H is

of the girder and ot varies between 0-15 and o.66. ~H is the
base of the
.cutout, in which 9 varies between 0.01 and 0.5. ~'H is the
base of the web,
vaying between 0.166 and 1.165. K varies between 0-015 and
3.333.
K_ varies between 0.25 and 4.6. Photoelastic tests for the
determina-
tion of isoclines have been made on plexiglass samples and for
the deter-
mination of isochromates on Dinox P-110 samples. Isoclines have
been es-
tablished in white light and recorded by drawing. Isochromates
have been
recorded by photographing in sodium monochromate light. The
device used
for bending tests is shown. The following observations have
been made on
the behavior and participation in distortion of different zones
of the gir-
der: The bases of the girders have formed an isoclinal zone of
00 para-
meter, except disturbances around the corners. The webs have a
similar
trend, not depending on their absolute dimensions for the same,
KI = -L 3atio.
In case of Klaol, the following categories of singular points
could be&ob-
served: a) internal singular points of the attractive type, one
in every
web, located in its center; b) Singular contour points of the
repulsive
type, one at every vertical side of the cutout. They indicate a
change of
the sign of stress on the contour and thus are neutral; c)
Singular corner
points located at every corner of the cutouts, being of II
order. In case

in
the middle of the verticals which limit the cutout, correspond to
some in-
flection points. The formation of.a neutral zope having a 2a height

important. The evdluation of-the unitary normal forces in the

tion of the web axis shows a Navier type diagram modified
by.the appearance.
of some hiCh neutral zones. In case of KI-41, the unitary
normal forces in
the external fiber of the vieb's transversal section is
superior to the'uni-
tary notmal stress in the external fibe37 of,the transversal
section in front
of the cutout, which is contrary to expectations. This is due
to the fact
that the inertia moment of the cutout section is smaller, so
that the uni-
tary normal force in the external.fiber is greater than in the
web's see-
tion. A calculation formula,for the unitary normal force in
the most
stressed section of the Yteb can easily be established.

expression (3)'is a
general form of the Navier's formula for the pure bending. In

ment can easily be computed. These nomograms also show that the
influence
of the cavities on the distortion produced by bending the tested
girders is
low. In case of K14,1, the distortions can be computed on the.basis
of the

T.---,'XT: The differential equation of the shearing forces in
upright
beams is establi8hedv and solutions are given for various types
of
loadings - uniformly distributed load (due to wind), triangular
load with its maximum at the diaphragm extremity (due to
seismic ac-
tion) and concentrated loads at the diaphragm extremity. In
all-ca-
ses the conclusions were verified by photoelastic models. The
method
of calculation is based on the hypothesis that the zone of the
row
of holes can be replaced by a strip with reduced elasticity
modulus,
obtaining thus a beam without holes with an inhomogeneous
structure.
The results are given in the forn of graphs. There are 10
figures.

TITLE; Investigations of load carrying building structure8
by means of plastic models
PERIODICAL: Revue de m6canique applique'e, v-7, no.4, 1962,
751-780.
'TEXT: The work of the INC~RC with model's made of plastics
for the stress analysis of building structures is reported. The
diversity of the methods used is emphasised since every method is
limited. Models of up to 1 m size are used in spite of differenpes
of behaviour on account of a higher Poisson's rattio in plastics
and
the unsuitability for destructive testing. Model laws have been
studied to determine the choice of materid1s and techniques and
the
interpretation of results. The conditions of similarity are
obtained from the equilibrium of an elementary slab, the geometric
relations between the deformations and displacements and the
physical relations between the stresses and strains. The
similarity
factors-are hereby determined only in parts the remaining factors
being chosen from the test conditions, including space available
and adequate deflections of the measuring devices.

The inexpensive investigation of many design variants is made
possible by model techniques. 1~xamples are discussed, including
several arch constructions, a circus roof structure, a multi-arch
factory roof and a restaurant structure. Distribution of load
carrying in complex statically indeterminate structures is among
the main features discoverable by models. Structural elements made
of composite materials have been examined by model techniques
including reinforced and pre-stressed concrete structural
elements,
pressure distributions when two bodies with a different Young's
modulus are in contact (for instance, a foundation on soil), and
the simplification of models by the replacement of cavities with a
material of low modulus. For example, the neutral axis of
reinforced concrete beams was examined on the assumption of an
ideal bond. Reinforced concrete beams in the condition of
incipient cracking, owing to a loss of bond in the section between
the cracks, have been tested by model techniques. Reinforced
models with artificial cracks were used, made from a material
specially developed at the Institute with a high optical activity,
a reduced edge effect, and a capacity to be bonded with adhesives

to the reinforcement consisting of high tensile steel wire. Two
types of crack were tested, namely with and without the capacity
to transmit compressive stresses. For large crack heights it was
found that the neutral axis coincides with-the tip of the crack
so that the crack does not propagate with an increase in the
load.~
Generally, photoelastic models-were found to behave in close
agreement with actual full-scale structures. Pre-stressed
complex
structures, such as the dome of the Bucharest State Circus
building, were model tested with strain gauges. Cavities can be
replaced by a material with a low equivalent shear modulus.
A wider range of materials is called for'wifh Young's moduli

ABSTRACT: The solubility of hydrogen (SH) in some ferrite and
austenite steels
and the effect of the individual alloying additions (W, V, Ti and
Cr)
on SH at a pressure of 100 atm and a temperature of 5000C are
investigated.
An installation is described for saturating metals with hydrogen
permitting
the fast cooling of samples from high temperatures to room
temperature
without reducing the gas pressure, The results obtained are
presented in
graphs and tables, from which follows the. small additions of W
(1.61%)
and V (0.45%) increase SH 5.5 times and twice, respectively,
an.admixture
of 0.48% Ti practically does not affect SH, and the
increase-in--the Cr
content to 13% increases SH only insignificantly. In alloyed steels
of
the wstenite class SH is by 4 times higher,than in carbon steel of
grade 20 and by 6 times higher than in alloyed steels of the ferrite

ABSTRACT:
This study was started under the supervision of
Professor

V. V. lpatlyev. Steel of type 40X (0.41% C; 0.85% Cr)

and melt 7475 (0-18% C; 3.05~6 Cr) were hardened and

subsequently tempered at various temperatures which

allowed the
obtaining of various Cr---ontent in the

carbide phase and solid
solution. The tests were made

in an autoclave under hydrogen
pressure of 800 atm. The

carbon content, structure, and
composition of the carbide

phase before and after the tests were
determined. The

composition of the carbide phase was determined

amount of chromium in the carbide phase increased with
the tempering temperature, and the rate of decarburiza-
tion decreased. Practically full decarburization was
achieved with tempering temperature equal to 550-7000 C.
Metallographic investigation showed that the size of

increased with the tempering temperature and with the

that steel with 0.18% C allqyed with up to 3% Cr resisted
the corrosive action of hydrogen better than steel 40X.
The investigated steels showed low resistance, however,
at 6ooo and 800 atm hydrogen pressure; evidently, the

bind all the carbon into carbides. Addition of 0.5-

basic formula used -

Eef. 1. The value
A' in this formula is a constant, the value B depends on the
change of the pressurq

dependence between t,~6 free term B and the pressure P at

following formula was
derived: B = n - lgP - Cl, where n - 1.12, C 1= 2.04. Using

0.12% C with
15.000/0 grains remained unaffected after 1,200 hours; after 3

depth of decarbonization was 3.8 mm. Identical steel with 500P

no signs of decarbonization after 8,800 hours, which confirms
the accuracy of
calculations of the length of the incubation period according
to Formula (1), i.e.
10,000 hours for fine-grained steel, According to the same
formula, the incuba-
tion period of carbon steel is 50,000 hours at 2200C and
800,000 hours at 1700C.
P. S. Perminov (Ref. 4: "Corrosion and its Prevention", vol. 2,
no. 1, 1936)
states that the tendency to fractures grows proportionally to
the increasing
carbon content of steel, owing to differing specific volumes of
cementite and
ferrite. Ref. 4 also contains data on the begin of hydrogen
corrosion of carbon
steel at various temperatures and pressures (Figure 2). From
reports contained
in References 3 and 4 follows, that at pressures up to 500 atm
the lower temper-
ature limit of hydrogen effect on carbon steel lies around
2000C. These results
have been confirmed by tests carbied out by the Gosudarstvennyy
Institut Vysokikh

nitrogen-hydrogen-
-ammonia medium at 300 atm and 450 - 52500. Similar corrosion
appeared in grade
"20' steel subjects to the same medium at 200 atm. The
unreliability of short-
-term tests is demonstrated by means of results obtained by the
GIVD with grade
"20" steel, and by a non-specified ammonia plant with carbon
steel.Acdording to the

author's calculations, the incubation period of grade 1120"
steel should be 10,000
hours at 150 - 250*C and 275 - 300 atm. Data obtained by F.
Nauman (Ref - 5, "steel
and Iron". Vol. 57, no. 32, 1937) is considered unreliable
because of the brief-
ness of pertinent tests (100 hours). Production experiments
confirm the accuracy
of results given in Ref. 4. and established temperature
limits and hydrogen pres-
sure in respect of various steels listed by G. A. Nelson
(Ref. 14: "Trans the
ASMR11, February, 1951). According to 0. van Rossum (Ref.
11:11Chem. Ing. Eng. ug
Teohn." vol. 25, no 8/9, 1953). Inner stresses and
preliminary cold working de-
crease the hydrogen resistance of steel, consequently carbon
steel should not be
used under pressures exceeding 300 atm and temperatures
above 2200C. This state-
ment is borne out by the findings given in References 4 and
14 and appears in re-
speot of smaller machine parts made of fine-grained steel.
The longer the soak-
ing of samples in hydrogen, the lower the temperatures and
pressures at which
fractures take place. The use of carbon steel in the shape
of coarse-gr&ined
large billets is particularly dangerous. Temperatures up to
1500C are considered
safe for carbon steel equipment used in hydrogenation
plants. For short-term
operations at higher temperatures, the strength of machinery
and pipe walls should
be :selected taking into account hydrogen corrosion. The
effective power of the

According to V.V. Ipatyev at al (Ref. 1: Zhurnal prikladnoy khimii,

TEM A method was developed for determining the hydrogen permeability
of IKhl8N9T (AIS1 3211 steel under high-temperaturit (up to
1,OOOOC) and high-pres-
sure (UP to 300 kgloe) conditions. It was found that the pressure
dependence of
the hydrogen diffusion rate in parabolic and the temperature
dependence is exponen-
tial, having p~ temperature coefficient of 21,650 oal-s-1,atom-1 .
The method
allows diffusion ratesthrough metals at high temperatures and
pressures to be de-
..termined with sufficient accuracy. It is essential that welding
joints can be X
avoided and the amount of diffused gas can be measured. The present
investiga-
tion was necessary since literature data refer only to tests at
high temperature
and low pressure or vice versa. No data are available for
high-temperature and
high-pressure conditions. In the method presented tubular samples
(Figure 1) are
used without welding joints and temperature and pressure were kept

the test. The testing assembly contained the diffusion unit, placed
into an elec-
tric oven, a high-pressure system and the device for measuring the
amount of dif-
fused-,hydrogen. In all experiments technical grade hydrogen gas was
used. The
sample (Figure 1) was instal-led into the diffusion unit by welding
the hydrogen
gas inlet-tube at point E to the sample and inserting the sample
into a vertical
cylindrical tube which was placed in the vertical electrical oven.
Hydrogen gas
thus entered into the sample and diffusion occurred through the
walls between
C-D (see Figure 1). From the cylindrical tube the diffused hydrogen
passed thralgh
an outlet-tube to the gas-measuring device. The high-pressure
assembly used in
the present experiments was-described in a previous paper (Ref. 10:
Tr. LTI. im.
LeAsoveta, Goskbimizdat,- XXXVIII, 2o4-215, 1957; Ref - 11: ZhPXh,
32, 12, 2667,
1959). The temperature wa's regulated during the experiments by
means of a3An-17
.(EDP-17) electronic potentiometer and registered by a3nn-og
(EPP-og) automatic
electronic potentiometer. The amount of diffused hydrogen was
measured in a de-
vice containing for smaller gas amounts a 2 Cm3 mioroburet
calibrated in 0.01 cm3,
while for greater gas quantities a 100 om3 buret graduated in 0.2
cm3 was used.
Measurementswere carried out in certain time interval and the amount
of diffused
gas was estimated per time,unit and for normal conditions. The
observation made
by P.L. Chang et. al. (Ref. 3; J. Iron and Steel Inst., 3, 170, 205,
1952) that

was proved in
preliminary experiments in the present work. Thus diffusion
charaoteristios were
estimated starting at high temperatures. The present tests were
carried out on
6 tubular samples made of 1Xhl8NqT steel. 0 following,temperatures
and 6rea-
sures were investigat%ld:.5000C and 300 kg/3, 600 - 8000C up to
200 kg/cm , at
9WC up to 100 kg/cd , 9500C up to 75 kg/cm2, and at 1,OOOOC up to
50 kg/om2.
The maximum difference in the results between the six imestigated
samples was
5 %. The results shown in Figure 3 and in a table indicate a
phriibolic diffusion
rate. In Figure 4 the temperature dependence of the diffusion rate
is demonstrat-
ed. Since all isobars in Figure

ABSTRACT: Steel strength drops significantly under the physical

action of hydrogen penetration, leading to the dissociation of
the carbide phase F
and to decarbonization. The present investigation considers the
influence of
separate alloying elements (cr, W, V, Nb, Ti), and also of the
combined action of
Cr and Mo, Cr and W. Cr and Nb, Cr and V, Cr and Ti on the
hydrogen stability of
steel at a temperature of 600C, hydrogen pressure of 600 atm and
test duration of
1,000-4,000 hours. It was shown that under conditions of high
temperature inter-
action with--hydrogen, steel with 0..15%C is not dec4bonized when
it contains 8.47.

have to be considered In evaluating materials working In a

(decarbonizatlon) and
hydrogen embrlttlemen~, the former being the most harmful. in

by the t)q)e of carbide i5ha~2the character of tl~e Interatomic
ties between carbon
and the alloying element, and secondar;ly by the velocity of

chromium-containing ferrite. Taits showed that additions of Cr,
Mo, W, V, Cb, and
71 Increase the stability of the carbide phase; at the same time,
the velocity
of carbide phase coagulation decreases. The degree of dispersion
of the carbide
component Is apparently not Important. To stabilize steel with
0.2% C, 3-6% Cr
against hydrogen corrosion (at 600 C), the addition of stronger
carbide-forming
elements such as V, Cb, and TI, or the addition of more than 9%
Cr, Is required.
However, at the present time, the authora are limiting their
recommendations for
the conditions 600C and 800 k9/cm2. Under such conditions, not
less than 8.4%
Cr should be added to steels with 0.2% C (or lessl and not less
than 10% Cr
should be added to steels with 0.2-0.4% carbon. There are not yet
sufficient
data available to establish a quantitative correlation between the
temperature i
and pressure, on the one hand, and the maximum hydrogen resistance
on the other.

TITLE. New Volumetric Method for the Determination of Uranium (Novyy
ob"yemnyy metod opredeleniya urana)
PEiIUDICAL: Zavodskaya laboratoriya, 1959, Vol 25, lir 7, ?P 789 -

ABSTRACT: The new method of determining uranium ras elaborati-d in
much
the sa:~ie ray as the determination of berylliai-i (Refs 10, 11).
The method is based upon a precipitation of uranium in the pre-
sence of trilon B with sodiuiA arsenate and a nubsequent i(;do-
metric titration of the
As03-_ ion bound Yith uranium. It ras experimentally determined
4
that the crystalline precipitate -,.hich is precipitated to acetic
uranium solution by addition of sodium arsenate (pHrsj3) possesses
constant composition (U02:AsO 1:1). The results of the iod,~-.
metric arsenic titration and ~Znversion into uranium (Table 1)
confir.-ned the applicability of this r3ethod to the determination
of uranium. The method described has a high selectivity since
the elements such as the bivalent metals FE;, Al, Bi, and V, Th,

hydrol and Zr by addition of fluoboric acid (Table 2) can be
bound. By addition of a lar.-er quantity of precipitant the
in-
fluEnce of the phosphates can also be eliminated. A process of
analysis is described. There are 2 tables and 1 Soviet
reference.

TITLE: Colorimetric method for determining zirconium in alloys
PERIODICAL% Zavodskaya laboratoriya, v. 27, no. 7, 1961, 795-797
TEXTs The methods, much improved recently, for determining
zirconium, e.
g., with pyrocatechol violet, xylenol blue, and Arsenazo III,
are subject
to the effect of various elements contained in the alloys
(Table 1). Tin
can be used as a reducing agent, particularly in strongly-acid
media in
which hydroxylamine and ascorbic acid are poorly efficient. In
the Arsenazo
III method, the presence of larger amounts of elements usually
admixed to
Zr is permissible. In strongly acid medium (2 N HC1), the
effect of all
bivalent, and many other, elements is eliminated. At a Zr
content ~0.1%,
Zr may be directly determined with Arsenazo III without removal
of Ti
(Table 2). The results obtained agree with control tests
performed with
pyrocatechol violet. The Ti content may be
