The Effects of Matrix Plasticity on the Thermal Deformation of Continuous Fiber Graphite/Metal Composites

摘要: The thermal deformation behavior of very low expansion, unidirectional and angle- ply metal matrix composites is investigated. theoretical investigation accounted for the plastic flow in material resulting from residual stresses ex posure to cyclic environment. Results indicate that varies significantly accordance with stress state material. Plasticity causes large strains hysteresis loops are not predicted by elastic analysis. effects plasticity can be minimized, however, increasing yield preconditioning composite consistent operating temperatures. This paper also includes test data substantiating elastoplastic as
