Abstract

AbstractThe expressions of the governing equations and the boundary conditions of an elastic body of orthotropic composite materials for the case of plane stress and plane strain conditions are different and for this reason the solutions would be different from one to another. Earlier the solutions of the present problem were obtained and studied considering plane stress condition. The present problem is solved considering plane strain concept analytically using Fourier series and numerically using Finite difference method (FDM). The different components of stresses at different sections of the plate obtained by the two methods are studied as a comparative manner. The comparative studies of the elastic field of the present problem using analytical and FD methods are carried out to verify the soundness of the present solutions. The theoretical background of the finite element method to solve this problem is in progress.KeywordsGoverning equationPlane strainBoundary conditions
