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.
