Metal matrix composites provide new materials with superior properties. They give high strength and stiffness. In this study, a stainless steel reinforced aluminum metal matrix laminated simple supported plate with a square hole is loaded transversely. Elastic, plastic, and residual stress analysis are calculated in the symmetric and antisymmetric cross-ply and angle-ply laminated plates for small deformations by using finite elements method. First-order shear deformation theory and nine nodes Lagrangian finite element are used. Load steps are chosen at 200, 400, and 600. Mechanical properties of a layer are obtained experimentally. The change of the residual stresses ?x and ?y from square hole to simple supported edge are shown as figures. © 2009 SAGE Publications.
