Abstract
Transformation toughened ceramics display a resistance to crack advance requiring an increasing level of applied stress intensity to advance the crack tip. In this paper the initial slope of the resistance curve is determined. Two material models are considered. In each, only a net dilatational transformation is considered. In one, the transformation is assumed to be triggered at a critical value of the mean stress. In the other, the transformation is assumed to take place when the maximum shear stress reaches a critical value.
