✦ Synopsis
Two novel techniques have been applied to the problem of determining the fracture toughness of polyethylene appropriate to the situation of rapid crack propagation in pipe systems. Agreement is found between the data from the two methods used for evaluating four grades of polyethylene of widely different toughness. By implication, either technique is valid for determining fracture toughness, but each method has a wider utility depending upon other evaluation requirements.
