Thermal Elastic-Plastic Stress Analysis on Simply Supported Aluminum Metal-Matrix Composite Laminated Plates

Abstract

In this study, thermal elastic-plastic stress analysis is carried out on simply supported symmetric cross-ply (0°/90°)2 and angle-ply (30°/-30°)2, (45°/-45°)2, (60°/-60°)2 aluminum metal matrix laminated plates. Tsai-Hill Criterion is used as a yield criterion. Differential equations are solved with a sufficiently large number of integration intervals of the temperature. The intensity of the residual stress components in the cross-ply laminated plate are higher than those in the angle-ply laminated plates. The residual stress component of the shear stress alone in the angle-ply laminated plates is different from zero.
