Fuselage Bending Calculations in the Region of a Mid-wing Junetion
the functions yi is obtained from the potential energy and the
Euler equations for the variational problem, This leads to a
differential equation of the form already encountered. The
maximum supplementary stresses are 9.,1;;% of the maximum fundamental
stresses on the boundary between the front and central sections
and 281A of these stresses on the boundary between the central and
rear sections. The supplementary tangential stresses are deter-
mined from the equilibrium condition. The supplementary stresses
diminish the bending moments in a reinforcea frame along its whole
perimoter. The correctness of the present simple method was
verified experimentally on a model of circular section loaded by
normal bending stresses which obeyed the plane law at its ends.
Theoretical and experimental investigations show that the reinforced
fraines are relieved of their loading as the cross-section becomes
less and less plane.

that a change of shape takes place in the transverse cross-

is simplified into a beam supported on end frames through two
load-earrying and a set of ordinary stringers in the central
plane. Simultaneously, with the shear stresses of the skint
stresses are observed also in the longitudinal cross-section of
the system if the stringers are considered as supported by the
end frames and loaded with the increments of the shear forces in
the skin. In ths initial system of foreest additional forces of
interaction between sections of the skin arise as well as those
bettween the stringers, and the skin. The conditions of compatibility

taken into account. The static indeterminacy is eliminatelby the
Ceistigliano method. It is assumed that the end frames, taking
into account the associated fuselage skin, have a large flexural
stiffitoss. The basic stresses are determined. As a rule, they
lead to warping of the cross-sections4 To remove the warping
which does not in f4ct take place beyond the limits of the central
cross-section, additional stresses are postulated. These are

TEXTi Pra,lti,7al formulas are derived for calculating ordinary and
sandwich circular shells, Arbitrary support conditions are assumed
and the external transverse load can vary in both longitudinal and
t.-ans-verse direotion; in a particular case, the shell may be loaded
by concentrated stresses. The normal stresses 0- are determined as
z
well ae the tangential stresseo q in the transverse.-cross section
elements. Simultaneously, the elementary circular sections (rings)
are ealculated, formed by the planes perpendicular to the z-axis.
The shell is considered as a statically indeterminate system. In
t
I 'lations, additional forces are taken into accowit, namely
he calou
those of interaction between the membranes and the shell, and be-
tween the rings. The solution of the problem is simplified by ex-
press-ing all the unknown internal stresses in terms of the bendang

PERIODICAL; Izvestiya vysshikh.vicb,ebnykh zavedeniy,
Aviatsionnaya tekhnika, no,40 1962, 79-90
TEXT: This is the first of' three articles. The calculations
are based on the assumption of ai structurally orthotropic shells
the force elements being-11smeared out". The energy method is used
to calculate the)critical stresses and it is assumed that under
the action of the critical external forces the system has both a
straight line and a curved form of' equilibrium, corresponding to
the minimum potential energy. The usual assumptions of the theory
of thin shells are made. Considering first the critical stresses
for the,axial form of the loss of stability, the nocessary
condition for the minimum potential energy leads to a fourth ordor
differential equation whose characteristic equation has roots
(a Pi). The displacements can increase without limit if
eith er a 0 or OL m7r, where L is the length of the shell.:;

From the first condition-can be obtained the critical axial
compressive stressl the second condition gives the number of half-
waves m along the generators at the loss of stability. The
transverse pressure has no effect on the critical stresses. In the
case of a non-axial form of the loss of stability, the assumption
that the cross-sectional axis remains fixed and the condition for
periodicity are used to give an expression for the tangential
displacementsiand the axial displacements are obtained from the
condition that the mean surface is not displaced. Using these
relations and the expression for the potential energy of unit
length of the cylinder, Euler's equation leads to a fourth order
differential equation which has the same complementary function as
the previous equation. From the conditioia a = o it is deduced
that positive (internal) pressure increases the critical stress
and negative pressure diminishes it., The condition pL = mn
gives a relation between the number of half-waves m along the
generators and the number n of waAres round the circumference at
loss of stability. Expressions for the critical stresses may be
obtained similarly for other boundary conditions. For the axial
form of the loss of stability the critical stresses increase with

The states of stress and strain of circular cylindrical ahplls stiffened by
stringers and rings are analyzed. The shells are subjected to tranoveri3al
loading combined with axial compression uniformly distributed along the
faces. The effect of manufacturing impBrfections of the shell's middle sur-
face is taken into account. The problem is discussed in a linear formulation
under conventional assumptions of the theory of elastic thin shells. For so-
lution of this statically indetermihatt! problem, Kanlo method,~eaolqying energy

and asymmetrical states of stress (caused by axisym-metrical and arbitrary

ABSTRACT: Noting that the loss of carrying capacity by a shell may be the result of
either the loss of stability or the breakdown of strength, tho author points out that there is,
no consensus with respect to the mechanism whereby the loss of shell stability occurs.
The author rejects the nonlinear approach to the determinallon of critical shell stresses
with allowance for considerable radial displacements on the part of system elements, and
advances the belief that it is physically more convincing, as well as mathematically correct,
to dotermino shell carrying capacity ftom linear positions while at the same time taking

into account the -nall initial bends of the surface. The entire aggre ate of irregularities
in the center surface of the system may be divided into tmro groups: Ese which correspond
to a stability loss In axiosymmetrical form and those which do so in nonaxiosymmetrical
form. Under the Influonce of external forces of compression the individual longitudinal
elements of the shell are found in a state of longitudinal- I.Tansverse flex-are. , All other
conditions being equal, the axiosymmetrical form of initial bending is the most dangerous.
Thus, the carrying capacity of the shell may be determined from the strength condition by
those external forces of compression, from which the sum internal stresses may reach the
yi-31d point of the material. It is noted, however, that this order of calculation will agree
with experimental data only in the event that the values of the radius- to-th! elmess ratio
(R16) of the shell are relatively small. In his analysis of what Viken place in the case of:
large R16 , the author advances the theory that the buckl'Llig moments of the individual
bands, with longitudinal- transverse flexure, may be considered the consequence not of the
roal initial axiosymmetrical bending of the surface, butof an equivalen'. imaginary
axiosymmetrical load, from which the shell loses stability in non-wdosymmotrical form.
Since the flexional rigidity of the shell elements is proportional to the cube of its thickness,
then, in the case of relatively large R/S (that is, in the case of small thiCknOBS Parameters)

shell stability loss Is extremely probable, with the compressfiig external ar;al load actively
promoting this phenomenon. On the basis of these phenomena, the author dorives the cal-
culation, formulas for shol'. oarrying capacity. The crippling Wal Btross, corresponding to
astan

necessary minimum value n must correspond to the whole number of halfwaves m along

capacity considers transverse loads, which may sharply reduce the carrying capacity of a

ABSTRACT: The final orbit of the 1951 X Arend comet has Wen determined from 41 ob-
servations carried out from October 1, 1951 to April 24, 1952. The per-
turbations from five planets have teen taken into consideration (Venus -
Saturn) . The mean error for one normal coordinate is C5 - 4' l".50. The
calculation of the perturbations ie continued for the next revolution of
the comet and the ephemeris of the comet is given for the period from
July 21, to December 28, 1959. The following systems of the elements were
obtained-.

structuref and the modification of the domain structure of films duriv
the magnetizing process. To summarize: (1) A very fine domain strucOre
appears on an increase of the angle between the direc.tion of.the de-
magnetizing process and the axis of caslest magnetizi:ng of the films;
(2) a structure consisting of coarse domain,s,, differing and undefined in
shape, was established in case of a fast demagnetization. A fine domain.
structure appeared on a slow demagnetitation. A stud's of magnetization
indicated that (1) domains 'grow abruptly on' thin (500 - 6oo X) and non-
uniform films; (2) on an increase of the film thickneSs and of the anglei
between the magnetic field and the direction of easie~3t magnetizing the
domai6 boundaries are shiN'ed uniformly in'ca'se,of'un:Lform films. in
case of a magnetization in the direction of difficult magnetizing the'
configuration of ihe domains does not change,kbut the contrasts between
the domains become weaker and disappear once saturation ie attained. The
contrast between the domains is restored in -part when the field is.discon-,
nected; (3) if a field -with the direction at 450 is applied, a brightenin~g,
of dark fields (or a darkening of bright fields) will be,observed. There

TITLE: Behavior of the domain structure of thin ferromagnetic films
at different temperatures

TEXTt This paper was presented at a conference on magnetism and antiferro-
magnetism. The anthors studied the behavior of the domain structure of
ferromagnetic films at different temperatures. Fe, Ni, Fe-Ni, and Fe-Ni-
Mo films were producedo b hot metal spraying in a vacuum (10- 5 mm Hg) on
to polished glass (350 C~ in a magnetic field of 120 oe. The optical de-
vice used for observation of the domain structure has already been descAlLed
(Ref. 11s Kirenskiy, L. V., Kan, S. V., Degtyarev, I. F., izv. Ali SS$R9
Ser. fiz., 25, no. 5 (1961)). The temperature dependence of the domain
structure was studied on a specially designed apparatus (Fig. 1) with whidi
the temperature in the specimens could be varied between -150 and +650 oc,

was kept at 10-3 mm Hg during the experiments. In the absence of magnetic
field the domain structure of all the specimens was highly stable. The
behavior of the domain structure at various different temperatures is
largely determined by the magnetic field strength. Magnetic reversal
nucleation unually occurs in some sections of the film at quite low tem-
peratures. With repeated magnetic reversal they are) easily reproducible.
At higher temperatures the number of nuclei increases, they grow, and the
boundaries begin to move more rapidly and smoothly. When nuclei are forafed
magnetic reversalcan only be achieved by increasing the temperature. H s
and H0 are temperature dependent. In some materialis they decrease as the
temperature rises. The curve for iron films at temperatures above 5000C
showed an dnomalous oourse, probably due to the different thermal expansion
of base and film. There are 4 figures and 11 referenoesi 3 Soviet and 8

TITLE: Hysteresis loops in flat ferromagnetic films
PERIODICAL: Fizika metallov i atetallovedeniyet v.14, no.6, 1962,
938-940
TEXT: There are no literary d4ta on the hysteresis of*isotropic
films. To fill this gap ferromagnetic filma were investigated
which were produced by thermal evaporatlon of iron and of an
alloy (17% Fe, 80a Ni, 3% Mo) from a tungsten crucible. The
metallic vapour beam was at an angle of 15'0 to the substrate.
Relatively thick iron films were deposited on glass discs (heated
to 300*0 in a magnetic field of 100 Oe, by evaporation from an
electrically heated iron wire. The metal layer was not 0overed
by a layer of it dielectric. The magnitude and the direction of'
the magnetization vector changed durin,,, cyclic remagnetization and..
hence the flux of reflected polarized light also changed. Using
the longitudinal Kerr effect by, revolving the specimen or the
remagnetization equipmentrelative to the plane of incident light.,
a series of loops could be obtained from a single film in the same~
way as if mutually perpendicular measuring coils were used, There

was good agreement between the hysteresis loops obtained for the
same film, Magneto-optically and by current methods. The
rectangularity of hysteresis loops and the coe:r,:.,ive force of a
2100 A' thick film showed no appreciable change on changing the
angle between the direction,of remagnetization and the plane of the'
incident light. Iron films exceeding 1000'k-were shown to be

and 450 A thick iron films, recorded from various sections of the--
films, showed that in the isotropic films the coercive force of
.both sections was 6 and 7 Oe, whilat in the anisotropic films
(vacuum-deposited from crucibles) the respective values were 27,7
and-30.8 Oe. The differences in the coercive force of individual
sections of the thin films were explained by the irregular
distribution of the nonuniformitics. A correspondence was
observed between the behaviour of the hysteresis loops and the
domain structure. Remagnetization in isotropic films was by
boundary displacement. The domain structure in very thin iron

ABSTRACT: Although there have been many experimental Investigations of the tempera-
ture dependence of the magmetio properties of ferromagnotic films, most of these,
however, have been concerned with the temperature dependence of the saturation mag-
netization. Yet the temperature dependence of other magnetic properties of thin
.filna ore also of interest, particularly in view of the fact that thin film memor-
ies are required to operate at temperatures in the range from -100 to 3000C. The
present work was concernod with Investigation of the hysteresis loops and domain

at different temperatureo. The domain structure was observed by means of the merl-
dional Kerr effects The permalloy'and cobalt films were prepared by vacuum evapo-
ration from a tungsten crucible in a 100 09 field. The iron films were evaporated
directly from an iron wire heated by passage of current. The films were deposited
on cover-glasses heated to l5,00C. The vacuum curing the evaporation operation was
about 8 x 10-6 mm Hge The hysteresis loops were recorded in the direction of the
axis of easy magnetization for different'directions of the applied field. The hys-
teresis loops for a 1600-1 thick cobalt film at temperatures from 20 to 3200C and
different directions of the iswitching field are reproduced in a figure. At room
temporatu~e the beat squareness ratio and the greatest value of the coercive force
in the easy magnetization direction are observed with the field applied In the same
direction (a w 00), Slight rotation of the reversing field gives rise to diator-
tion of the horizontal sections of the loop, which is indicative of rotation pro-
cesses. With increase in temperature the loops narrow. 'rho initial properties of
the film are not ro-established upon cooling to room temparature. The behavior of
Mo permalloy films in diffe2vnti these films retain their anisotropy after heating
and coolings. The coercive force versus temperature curves obtained for the diffe-
rent films are reproduced in Fig6l of the Enclosure. Photographs of tho domain

.1structure on the (001) surface of iron whiskers (100 to 200 micron diameter) grown
in the [1103 direction. The report is illustrated with 47 reproductions of domain
structure photographs. Among the different kinds of behavior of domain structure
'mentioned or discussed are the following. When iron crystals are magnetized in the
;easy direction, the process of domain wall motion stops short of saturation, and the
remaining narrou'unfavored domains disappear suddenly. When the magnatizidg-field
makes a sufficiently great angle with the preferred magnetization directions; initin
magnetization takes place by domain wall shift; this is followed by a restructuring
of the domains, after which further wall shifting occurs. The final approach to sa--
I
turation is by ordinary rotation. The herring bone or fir tree domain structure Oil

Idomains. The size of the domains in cobalt films Increases with the rate of do-
magnetization by alternating field. This is related to the formation of wodgo
shapod domains, ona within another. When a thin cobalt film is cooled from above

Iwall shift during traversal of an asymmetric hysteresis loop in the presence of
