A single specimen J-integral method has been used to evaluate the critical energy for crack initiation in rubber-toughened poly(methyi methacrylate). An abrupt transition is observed in the evolution of J~c as a function of particle volume fraction and the sudden increase in toughness appears to be directly related to a comparable change in the materials's ability to nucleate plasticity.
