Crack growth resistance in MgO-partially-stabilized ZrO{sub 2} (Mg-PSZ) has been studied using notched double-cantilever beams (DCN's). High-toughness Mg-PSZ exhibited nonlinear mechanical behavior in the form of residual displacements, related to the transformation of tetragonal (t) ZrO{sub 2} precipitates to monoclinic (m) symmetry. The influence of this residual displacement on crack resistance behavior has been analyzed using several different fracture mechanics approaches.
