Elasto-plastic stress analysis in stainless steel fiber reinforced aluminum metal matrix laminated plates loaded transversely

Metal matrix composites provide new materials with superior properties. The y give high strength and stiffness. In this study, a stainless steel fiber reinforced aluminum metal matrix laminated simple supported plate is loaded transversely. Elasto-plastic stress analysis is carried out in the laminat ed plate by using finite element technique. The expansion of plastic zone a nd residual stresses are determined in the symmetric and/or antisymmetric c ross-ply and angle-ply laminated plates for small deformations. Iteration n umbers are chosen as 100, 150 and 200. The yield points in symmetric lamina tes are higher than those in antisymmetric laminates. (C) 1998 Elsevier Sci ence Ltd. All rights reserved.
