In this study, thermal elastic-plastic stress analysis is carried out on simply supported symmetric cross-ply (0degrees/90degrees)(2) and angle-ply (30degrees/-30degrees)(2), (45degrees/-45degrees)(2), (60degrees/-60degrees)(2) aluminum metal-matrix laminated plates under a linear temperature distribution across the thickness of plates. The temperature distribution is chosen as T-0 and zero at the lower and upper surfaces, respectively. Tsai-Hill theory 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 of sigma(x) and sigma(y) is the highest at the upper and lower surfaces. Plastic yielding occurs in all the laminated plates at the same temperature.
