摘要：
Fracture parameters such as crack velocity a, stress intensity factor K(d) and a specific crack extension resistance R* were measured for Homalite-100, PMMA and epoxy in the course of fast crack propagation using a Cranz-Schardin type high speed camera. Fracture surface roughness lambda was evaluated as a function of crack length a so that it could be correlated with the fracture parameters above. The results showed that none of those parameters could be uniquely related to lambda. Instead, there was a good correlation between lambda and a product R* a.
