EFFECTS OF NONUNIFORMITY OF FIBER DISTRIBUTION ON THERMALLY-INDUCED RESIDUAL-STRESSES AND CRACKING IN CERAMIC-MATRIX COMPOSITES Academic Article

abstract

• A three-dimensional finite element analysis is conducted to estimate stresses induced by thermal cooldown in unidirectionally fiber-reinforced ceramic matrix composites. Various configurations of nonuniform fiber distributions are considered. Both cases of thermal expansion mismatch between isotropic, linearly thermoelastic fibers and matrix are studied. Significant effects of nonuniformity of fiber distributions on the local stress states are found. The initiation of various possible cracking modes is discussed in the light of these results. 1993.
