摘要：

The stress response of a titanium aluminide/silicon carbide-fiber-reinforced metal-matrix composite has been studied. The investigation was conducted using a two-dimensional axisymmetric finite element model of a unit cell of the composite. The model was generated with the ADINA-IN finite element program preprocessor. A strain-rate dependent unified state variable constitutive model was implemented into the ADINA finite element program to analyze the materials time-dependent inelastic response. The composite system was subjected to various time-dependent cooling profiles in an effort to reduce the residual stresses that initiate radial cracks in the matrix. The cracks originate at the fiber-matrix interface as the material is cooled from its consolidation temperature to room temperature.
