This book was released on 1963 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper offers a practical solution of the complicated equations for the deflections of nonorthotropic plates; in this discussion plywood plates made of Douglas fir are considered. The intricate partial differential equations are expressed in terms of finite differences. The simultaneous algebraic linear equations thus obtained are easily solved. The theory of obtaining the required elastic constants for the plywood plates is discussed in the introduction. The theory is expanded in Appendix IV by developing the general expression for the deflection of a thin plate. This expression is used in the experimental methods for obtaining the elastic constants. Part I explains the tests performed on the plywood plates to derive the elastic constants. The plates were cut with the face grain making angles of 0, 22 1/2, 45, 67 1/2, and 90 degrees with the coordinate axes. Bending and torsion tests were conducted on each plate. Three means of supporting the plates in the bending tests were investigated in order to determine the method which would give the most reliable values for the elastic constants. The nonorthotropic plate equation is expressed in terms of finite-difference equations for uniformly loaded and simply supported plates in Part II. These equations are simplified considerably by the considerations of the symmetry that is possessed by the plywood plates. The complete derivation of the nonorthtropic plate equation is given in Appendix III. The theory for the deflections of plywood plates is verified in Part III byconducting experiments on uniformly loaded and simply supported plates. The theoretical and the experimental values of the deflections are compared in a tabulated form; the discrepancy, which varies from 23 to 38 percent, is also indicated. Sample calculations for the elastic constants are included in Appendix I. The generalized Hooke's law is discussed in Appendix II. Also, the stress and strain equations applied to plywood plates are included.

This book was released on 1951 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: The differential equations of the bending of sandwich plates were integrated to obtain the deflections when the four edges of the plate are simply supported and the loading consists of either a uniformly distributed transverse load or a concentrated load applied at the center of the panel. The deflection patterns are shown in diagrams and the maximum deflection of the plate is presented in a number of graphs.

Available in PDF, EPUB and Kindle. Book excerpt: A digital computer program was developed to find the buckling coefficient for rectangular plates with all edges simply supported or with all edges clamped. A finite difference technique is used to solve the partial differential equation for the deflection of a plate classically treated as having only a small deflection compared to its thickness. The program was prepared to take for an input the stresses at nodes formed by grids dividing the plate into rectangles. The stresses and deflections at each node are used in writing difference equations. An extrapolation formula is featured in the program which allows a close approximation to the buckling coefficient without necessitating the use of a large number of grid nodes. The program was written in FORTRAN 60 but must be used as a FORTRAN 63 program to take advantage of some of its inherent flexibilities. Information is provided in the output of the program which aids in evaluating the reliability of a solution. (Author).
