Abstract

In the continuum mechanics framework, the transformation plastic localization phenomena observed in zirconia ceramics is analysed by using the micromechanics model of Sun, Hwang and Yu (Journal Mech. Phys. Solids 1991 39, 507). The condition for the onset of localization is derived and the orientation of localization is predicted. The analytic results are compared with the available experimental observations on the localization in ceramics under uniaxial loading and good agreement is found.
