Residual stress analysis and plastic zone behavior in antisymmetric metal-matrix laminated composite plates

This paper presents a residual stress analysis and plastic zone behavior in antisymmetric aluminum metal-matrix laminated plates. First-order shear deformation theory and Finite Element Method are considered in the solution for small deformations. The plate is meshed into 64 elements and 289 nodes with both simply supported or clamped boundary conditions. Stainless steel fiber reinforced aluminum metal-matrix laminated plates of constant thickness are formed by stacking four layers bonded antisymmetrically. It is assumed that the laminated plates are subjected to transverse uniform loads. Loading is gradually increased from yield point of the plate as 0.0001 MPa at each load step. Load steps are chosen as 100, 150 and 200.
