Interlaminar Stresses in Symmetric Composite Laminates

Abstract

Interlaminar stresses and displacements of each layer satisfying geo metrical boundary conditions are represented in series of Legendre poly nomials. The extended Galerkin procedure is used for each layer, and the final solutions are obtained by requiring the satisfaction of continuity conditions at each interface and the stress boundary conditions at exterior planes. A computer program has been prepared, and numerical results are presented and compared with existing data.
