Abstract: The influence of temperature and strain rate upon the fracture toughness of structural steel is the question considered in this paper. The hypothesis is proposed that fracture toughness, KIc , ...

Abstract: An important fracture mechanics problem is the determination of fracture toughness values with small specimens that fail after yielding. The J integral has an explicit meaning in terms of notch ...

Abstract: A simple and convenient method of analysis for studying two-dimensional mixed-mode crack problems is presented. The analysis is formulated on the basis of conservation laws of elasticity and of ...
