In this study, a thermal elastic-plastic stress analysis is carried out on simply supported symmetric cross-ply (0°/90°) 2 and angle-ply (5°/85°) 2 , (15°/-15°) 2 , (30°/-30°) 2 , (45°/-45°) 2 , (60°/-60°) 2 , (15°/60°) 2 , (15°/75°) 2 , (75°/-75°) 2 aluminum metal-matrix laminated plates under the uniform temperature distribution across the thickness of the plates. The 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 composite material is assumed to be strain hardening linearly. The magnitude of the residual stress components in the cross-ply laminated plate are higher than those in the angle-ply laminated plates. Plastic yielding occurs in all the laminated plates at the same temperature.
