Abstract

Crack branching in Araldite d and Homalite-911 was studied using a modified Cranz-Schardin type high speed camera which provided simultaneously taken shadow patterns and specimen-focussed images. Fracture parameters including crack velocity a, stress intensity factor Kd and specific crack extension resistance R{six pointed black star} were measured in the course of crack propagation. No definite critical values could be determined with one of those fracture parameters for the onset of crack branching. Instead, the product R{six pointed black star}a, i.e., energy per unit crack width per unit time, was found to have a critical value for the branching.
