Research of Microstructurally Developed Toughening Mechanisms in Ceramics. Part 2. Contribution to Fracture Toughness.

Abstract

The first part of this series described the thermodynamics of the constrained phase transformation with particular emphasis on the effect of the inclusion size. In this part, two different approaches, viz. Griffith's and Irwin's, will be used to determine the contribution of a stress-induced phase transformation to the fracture toughness of a brittle material. As in Part 1, special reference will be made to the ZrO2 (tetragonal) yields ZrO2 (monoclinic) transformation.
