Abstract

In this paper we trace the development of transition fracture toughness models from the landmark paper of Ritchie, Knott, and Rice in 1973 up through the current day. While such models have become considerably more sophisticated since 1973, none have achieved the goal of blindly predicting fracture toughness data. In this paper we suggest one possible way to obtain such a predictive model.
