Mode I crack growth is studied in ceramics which undergo a stress-induced martensitic phase transformation that leads to a substantial increase of toughness. The transformation involves both dilatant and shear transformation strains. Full crack growth analyses are carried out numerically and it is demonstrated that the transformation shear strains are a major contribution to toughening.
