Analysis of the Effect of Transformation-Induced Shear Strains on Stability and Crack Growth in Zirconia-Containing Ceramics

Source

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.
