Elastic-Plastic Stress Analysis of Metal Matrix Laminated Plates under In-Plane and Transverse Loading

摘要

Metal matrix composites reinforced by fibers give high strengths. specific stiffness. ductility. yield point and a good temperature performance. They provide a rela- tively new way of strengthening metals. ln recent years several low cost manufacturing tech- niques have been developed. In this study. continuous stainless steel reinforced aluminum matrix composite manufac- tured by die casting process has b~en used as a simply suppol1ed symmetric and antisymmetric laminated plate loaded by in-plane and transverse forces. An elastic-plastic numerical solution has been carried out by finite element technique tor several iteration numbers. Residual stresses and the expansion of the plastic zone have been illustrated in ta- bles and figures.
