摘要：

An approach to the nonlinear stress-strain behavior of ceramic matrix composites was proposed, based upon damage mechanics. Damage-loading relations taking into account effects of anisotropy and coupling were established. These relations allowed prediction of the stress-strain behavior, and ultimate failure. The theory was then applied to a 2D SiC/SiC composite subject to tensile loading under 0-degrees, 20-degrees, and 45-degrees off-axis angles. A two-stage damage mechanism was identified by optical microscopy on specimens under load. Predictions of the stress-strain behavior were in excellent agreement with experimental data.
