Abstract
Fracture parameters such as crack velocity à, stress intensity factor Kd 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 λ 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 λ. Instead, there was a good correlation between λ and a product R*à.
