In this study, a thermal elastic-plastic stress analysis is carried out on steel-fiber-reinforced aluminum metal-matrix composite laminated plates fixed at all edges. Temperature is chosen to vary parabollically. It is zero and To on the middle axis and at the upper-lower surfaces, respectively. The solution is executed for symmetric cross-ply (0degrees/90degrees)(2) and angle-ply (30degrees/-30degrees)(2), (45degrees/-45degrees)(2), (60degrees/-60degrees)(2) laminated plates. The elastic-plastic solution is carried out for small plastic deformations. The Tsai-Hill Theory is used as a yield criterion. Residual stress distributions along the thickness of the plates are obtained. All the residual stress components are in static balance with respect to middle plane of the laminates since they are symmetric in opposite signs.
