Fiber-reinforced metal-matrix composites provide high strength, ductility, specific stiffness, yield point, and a good temperature performance. In this study, steel fiber-reinforced aluminum metal-matrix composite-laminated plates are loaded under in-plane and transverse forces. The finite element method is used for obtaining the solution. The Tsai-Hill theory is used as a yield criterion. The laminated plates are oriented symmetrically and antisymmetrically. The orientation angles are chosen as (0°/90°)2, (15°/-15°)2, (30°/-30°)2, (45°/-45°)2, (60°/-60°)2, (75°/-75°)2, (0°/15°)2, (0°/30°)2, (0°/45°)2, (0°/60°)2, and (0°/75°)2 for the in-plane loading. The stress components are calculated for 500 and 700 load steps. The in-plane force is increased 0.08 (N/mm) per step. The transverse loading is carried out on symmetric and antisymmetric (0°/90°)2, (30°/-30°)2, (45°/ -45°)2, and (60°/-60°)2 laminated plates. The expansion of the plastic region is carried out for 100, 300, and 500 load steps. The magnitude of the residual stress components at the midpoint of the plates for different orientation angles are calculated. [ABSTRACT FROM AUTHOR] |
