ABSTRACT
In this chapter, high-temperature multiple matrix cracking behavior in ceramic-matrix composites (CMCs) was investigated. A critical matrix strain energy (CMSE) criterion was adopted to determine the matrix cracking density for the damage state of interface partial and complete debonding. Experimental matrix cracking density and interface damage state of SiC/SiC composites for different temperatures were predicted. Effects of composite's constituent properties on temperature/time-dependent matrix multiple cracking evolution were discussed. Relationships between composite's constituent properties, temperature, and applied stress level of CMCs were also established.
