Abstract

In this chapter, damage mechanisms and damage models of fiber–reinforced ceramic–matrix composites (CMCs) under mechanical loading are analyzed. Matrix cracking, interface debonding, and fiber failure are the main reasons for contributing to the nonlinear behavior of fiber–reinforced CMCs. The related damage models for matrix cracking, interface debonding, and fiber failure are also introduced. Effects of fiber volume, interface properties, and fiber’s Weibull modulus, and fiber’s strength on the first matrix cracking stress and matrix multiple cracking are also analyzed.
