摘要：
A single specimen J-integral method has been used to evaluate the critical energy for crack initiation in rubber-toughened poly(methyl methacrylate). An abrupt transition is observed in the evolution of J(Ic) 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,
