CRACKING DUE TO EIGEN STRAINS OF A CIRCULAR INCLUSION IN CERAMIC MATERIALS
陶瓷材料中圆形夹杂的本征应变导致的微开裂

The microcracks caused by the transforming inclusions associate closely with the mechanism of fracture and toughness in ceramic materials. Exact analytical expressions for dislocation density, opening displacement and stress intensity factors of microcracks in the matrix, caused by a circular transforming inclusion, have been derived by using dislocation theory method. The results obtained have been analyzed and discussed.
