In this study, a thermal elastic-plastic stress analysis is carried out on simply supported symmetric cross-ply (0degrees/90degrees)(2) and angle-ply (5degrees/85degrees)(2), (15degrees/-15degrees)(2), (30degrees/-30degrees)(2), (45degrees/-45degrees)(2), (60degrees/60degrees)(2), (15degrees/60degrees)(2), (15degrees/75degrees)(2), (75degrees/-75degrees)(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.
