MICROMECHANICAL ANALYSIS OF A CONTINUOUS FIBER METAL-MATRIX COMPOSITE INCLUDING THE EFFECTS OF MATRIX VISCOPLASTICITY AND EVOLVING DAMAGE Academic Article

abstract

• A thermomechanical analysis of a metal matrix continuous fiber composite is performed herein. The analysis includes the effects of matrix inelasticity and interface cracking. Due to these nonlinearities, the analysis is performed computationally using the finite element method. Matrix inelasticity is modeled with a rate dependent viscoplasticity model. Interface fracture is modeled by the use of a nonlinear interface constitutive model. The problem formulation is summarized, and results are given for a typical SiC-Ti composite at elevated temperature. Preliminary results indicate that rate dependent viscoplasticity can be a significant mechanism for dissipating the energy available for interface fracture, thus contributing to improved macroscopic ductility of the composite. 1994.
