Abstract

Computational procedures are described to evaluate the behavior of high-temperature metal-matrix composites. Typical results are presented from studies done on compliant layers to reduce the residual thermal micro-stresses and the effect of partial bonding on composite properties. A three-dimensional finite element analysis in conjunction with strain energy release rates is also described to evaluate composite microfracture. Typical results for micro-fracture in composites subjected to thermo-mechanical cyclic loading are discussed and presented. The results show that interfacial debonding follows fiber or matrix micro-fracture.
