Thermal ElasticPlastic Stress Analysis of Aluminum MetalMatrix Composite Laminated Plates Under a Parabollically Temperature DistributionDepartment of Mechanical Engineering Pamukkale University Denizli, Turkey
Department of Mechanical Engineering Süleyman Demirel University Isparta, Turkey In this study, a thermal elasticplastic stress analysis is carried out on steel-fiberreinforced aluminum metalmatrix composite laminated plates fixed at all edges. Temperature is chosen to vary parabollically. It is zero and T0 on the middle axis and at the upperlower surfaces, respectively. The solution is executed for symmetric cross-ply (0° /90°)2 and angle-ply (30° / -30°)2, (45° / -45°)2, (60° / -60°)2 laminated plates. The elasticplastic solution is carried out for small plastic deformations. The TsaiHill 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.
