These functions are: three components of the displacement vector u0 = u(x1yM' vo = v(xYO) and wo = W(XyO) and three components of the stress vector X = X (Xlylo)~ Yo = Y (x.4 0 2 z ..1,0) and z0 = ZZ(xTy?O) If all these six initial functions are known,all displacements and stresses in the plate can be expressed in the form of an infinite series of terms in Card 1/4 z , the coefficientB of the terms being simply the initial SOV/24-58-7-6/36 Application of the Method of Initial Punctions to Problems of EquilYLbrium of Thick Multilayer Plates functions and their derivatives Vith respect to x and y , as given in Eq (0.1). The expressions determining the differential operators L, A, B and C are given in Ref 1. They all include the Poisson's coefficient V an&the shear modulus G . Eq (0.1) neglects inertia forces. If. for convenience,, a new system of symbols be introduced as given by the terms startin.- with u(x,Y,Z) = Ul , on p 40, and ending with Zo =.U6 then Eq (0.1) can be simply express(..,d as a single sum (Eq (0.2). The author then considers some particular cases. Starting with a flat multi-layer plate (Figure 1), it is assumed that deflections and stresses change in a continuous manner, hence the final values for the first layer become the initial values for the second and so on. This leads to a number of matrices, which, when solved, give the answer to the problem. In the'case of a two- dimensional problpm, e.g. in the xz-plane, we have v = 0 and therefore neither u nor w do depend upon y . Card 2/4 The problem simpl-.fies and instead of the 9 terms in the SOV/24-58-7-6/36 Application of the Method of Initial Functions to Problems of Equilibrium of Thick Multilajer Plates sum of Eq (0.2), Only 5 terms remain as shown in Eq (2.1), Detailea determinations of the operators Lik are given in Ref 2 and are summarised in Eq (2.2). Symbol y in these expressions denotes the partial derivative 2vllx . In order to obtain displacements and stresses in terms of the initial functions (which will be in the form of infinite series) it is necessary to expand the trigonometric functions as a seri -es in poars of yz then replacing y by 21/.jx 1 to perform the differenti- ation of the respective initial functions. As an example, the author solves the problem of an infixdte plate consisting of two layers and resting- on a-great number of identical and equally spaced supports (Figure 2) at first in general terms and then for the case of uniformly distributed load q . In the latter case., the graphs of Figure 3 represent the normal stresses U 3 = Zz and U5 m' Xx at the mid-section (x = 1/2a) of the span (graphs a and b , respectively) Card 3/4 SOV/24-58-7-6/36 Application of the Method of Initial Functions to Problems of Equilibrium of Thick Multilayer Plates for the following conditions-. h, =11 h = 1/4!, a -.= 1/61 G = 1OG V'1 =_ '02 =: 0 - 3 2 2 1 The alithor considerg also the same case as before but with -the plates jtree to slide with respect to each other at 16-he sxrface of contact.

This method consists of finding four basic functions u(x'O) = U01 W(X,O) = w 0, xz(x,O) = X 0 and Zz (x'0) = z0 which represent the corresponding components of the dislocation and tension vectors at the point Z = 0. The basic functions in this case are defined as Eq (0.1), where Z and X represent the tensions Z z and X z; U, U 0 and W, W0 correspond to the displacements U = Gu, U0 = GU 0t Card 1/4 W = Gw and W 0 = Gwol where G - modulus of shear. SOV/179-59-3-16/45 An Application of the Method of Basic Functions in the Theory of Elasticity of Rectangular Systems These values will be called displacements. The differential operators L and A in their symbolic terms are defined as Eq (0.2), where y is a constant. Three cases are considered. In the first case the homogeneous conditions of the mixed type are acting on the two opposite sides of the rectangular surface. The limiting conditions in this case are expressed by Eq (1.1) and the basic functions U0 and Z 0 are equal to 0. The remaining two functions can be defined as Eq (1.2), which can be written in the general form as Eq (1.8) if the function F(x) is introduced as in Eq (1-3). These two functions can be represented as Eqs (1.14) and (1.16) when the transforma- tions, Eqs (1.9) to (1.13) and (1.15), are effected. The second case is defined for the homogeneous static conditions on two opposite sides when the limiting conditions are expressed by Eq (2.1)., In this case the basic functions X 0 and Z 0 are alSo equal to 0 and the other two functions are represented by Eq (2.2). Card 2/4 Similarly, as in the previous case, the function F(x) is SOV/179-59-3-16/45 An Application of the Method of Basic Functions in the Theory of Elasticity of Rectangular Systems introduced (Eq 2.3) and the formulae,Eq (2.6), are defined (where C I = const). Substituting Eq (2.6) into Eq (0.1), the general formulae (2-7) are obtained which correspond to Eq (2.5). The value of kh in Eq (2-5) is expressed as kh = a + bi and then it is divided into two equations, Eq (2.8). Alfio the values of a-bi, -a+bi and -a-bi can be obtained and, therefore, Eq (2-5) can be written as Eq (2.9). The values of a and b were found experimentally by 1. Fadle (Ref 8) and are tabulated on p 121. Since the general form of the function F(x) can be written as Eq (2.10), the complex roots of Eq (2-5) are obtained as Eq (2.11) or (2-13). The third case is obtaitLOd when the homogeneous geometric conditions (3-1) are affectIng two opposite sides. The function F(x) in this case is defined as Eq (3.2) which, in contrast to Eqs (1-5) and (2.5), does not contain zero roots. Therefore, the general integral for F is determined similarly to Eq (2.11). Then, the integrals for displacement and tension are found from Card 3/4 Eqs (2.14) and (2.15) for the limiting conditions SOV/179-59-3-16/45 An Application of the Method of Basic Functions in the Theory of Elasticity of Rectangular Systems (P -jk2 0 + 1 (P I + 1 (P 0 for z = 0, z = h 2) 2k2 It should be noted that the calculations shown in this ifork (such as Eqs (1.14), (1.16) etc.) could be extended to every plane surface having at least two parallel sides. There are 1 figure and 9 references, 6 of which are Soviet and 3 English.

(Ref 1), the fundamental relationships.of the methods,of initial functions,are derived for the axially symmetrical problem of the theory of elasticity. A similar method was given by A.I. Lurlye (Ref 2). An arbitrary S-olid of revolution under conditions of axially symmetrical deformation is-considered under the action of external loads without mass~forces.. The displacement vector components in a cylindrical coordinate system are multiplied by the shear modulus and, in this form, are called displacements in the initial function method. The initial functions are the values in the base plane of the displacement vector and stress vector components. On the assumption that the stress and strain distributions are independant of the angular coordinate, the general expressions for the Card 1/3 93907 S/179/0/000/005/010/010 R191/E181 The Method of Initial Functions in the Axially Symnetrical Problem of the Theory of Elasticity displacements and stresses of the initial function method, formulated earlier in cartesian coordinatea, are transformed. Two basic sets of relations exist of which one applies to symmetrical and the other to anti-symmetrical deformations (torsion problem). The derivations are applied to the torsion of a thick- walled cylinder subject to an arbitrary torsion loading applied to the far end face of a.cylinder fixed at the other end face. The torsion load is distributed over the face In accoodance with a given function of the radius. To satisfy the boundary conditions at the loaded face, a, differential equation of infinite order is formulated. The solution, being the sum of a particular solution of th,encn-homogeneous equation and the general solution of the homogeneous equation, is stated. The solution is expressed by Bessel functions, but when the radial distribution of the end load obeys a certain law, elementary functions are applicable. The application of the method is shown to the problem of the equilibrium of a thick-walled cylinder with "mixed" boundary Card 2/3 93907 S/179/60/000/005/010/010 E191/E181 The Method of Initial Functions in the Axially Symmetrical Problem of the Theory of Elasticity conditions at the end faces (vanishing axial deformations and shear stresses). It is shown that identical solutions are obtained with those already given by other methods of the theory of elasticity. If the boundary conditions at both end faces are expressed in terms of stress alone (vanishing axial and shear stresses), the problem becomes that of the flexure of & round plate under an axially symmetrical load. The problem is solved by considering two partial solutions which are superimposed. Finally, the problem is considered of arbitrary normal loads at one face whilst the other face is free of either load or fixing. There are 7 Soviet references.

SOV/6428 analysi's of thin-walled structures under static and dynamic loading. COVERAGE:, The general theory of strength, stability,,and vibration of thin-walled beams andicolumns of open and closed cross;section is presented. The design of solid-cross-section bars is also discussed. The following m6dern problems of the strength of ma- terials, structural. me6hanics, and applied elasticity theory are examined: thin-walled, shell-type open-bection beams reinforced by transverse elements; shell-type closed-section 0eams undergoing normal:_and shearing strains due to the iiarping of cross sections; Oestressed beams; thermal stresses; equilibrium of shell-type beams under complex loadings; three-dimerisiOnal stability; and vibration of thin-walled structures. Thei treatment of all these goblems is. based ontthe eneral "bimoment" theory of warping deplanation). The erm bimoment" denotes a pew quantity in statidis (dimensionality kg.CM2) associated,with the sectorial deplanation of the Pross section.

Superheated steam at a calculated expansion ratio of P.*/P2 14 was used.- The affioiency as a function of u/Co for drilled nozzles is shown in Fig, 2 of the Enclosure, for milled nozzles in Fig, 3 of the Enclosurep, while a comparison,of economy of the two types of nozzles as a function of F min is shown in Fig. 4 of. the Enclosure. It was found that the admission ratio rather than. a 1 had the major effect on efficiency for the drilled nozzles, while for the milled nozzles the efficieney,depended on the type of construction at small admission ratios (Z = 1). This dependence decreased as Z was increased (Z = 4), I-The efficienev of drilled nozzles was found to be greater (see Fig. 4 of -the En- 9) than that of milled nozzles over the whole range of investigated paran- clo'Our eters.

Using the equation by Gibbs.-Duhem a possibility for tile calculation of the magnitude of the mean "practical" ion activity coefficient y� is given for the case of the determination of the values of the activity of water for higher concentrations of the electrolytes employing the data already existing in this field. The isopieatic method by Robinson and Sinclair (Ref 1) was employed for the determination of the water activity; Card 1/3 Kharned and Ouen (Ref 2) had proved the reliability of this The Osmotic and Activity Coefficients of' RbCl, CsC1 and SOV,/76-32-7-2jc/,1.5 Kj in Highly Concentrated Aqueous Solutions method.-Ther diagram of the vacuum exsiccator used is given, from which fact may, among other thin.ms, be seen that glass and silver vessels were used~ The water activity was determined, according to calibration curves with NaCl and CaCl 2 solutions being uaed. The activity coefficients and the osmotic coefficients were calculated according 'to an equation. Besides the KJ-, NaCl- and CaCl 2- salts used also the method employed for the production of RbCl and CsCl is described. The inves- tigation of the solubility of the salts was carried out according to the isopiestic method. The obtained values of the solubility at 2509 as well as those of the osmotic and activity coefficients are given in a 'table. There are 1 figure, .1 table, and 5 references, I of which is Soviet.
