Summary

The use of fracture mechanics to gain insight into failure of ceramic composites is 2illustrated by considering the tensile failure of a composite containing unidirectional continuous fibers. Observations of failure mechanisms are reviewed and a fracture mechanics analysis of the initial stage of failure (matrix cracking) is described. The analysis provides relations between the matrix-cracking stress, the microstructural parameters, and the size of preexisting defects.
