Abstract
Stabilized zirconia ceramics can undergo a stress-induced tetragonal-to-monoclinic phase transformation. A transformation zone with compressive stresses develops at crack tips, leading to an increased fracture toughness which depends on the size and geometry of the transformation zone. In this paper, transformation zones in cracked and uncracked bodies for the case of autocatalytic phase transformation are computed using the weight function method and Eshelby's method. The results are compared with experimentally observed transformation zones.
