摘要：

An elasto-plastic analysis of a compact mode II fracture specimen is performed. Both an approximate approach with rigid plastic material and a more exact elasto-plastic finite element calculation are carried out. From this analysis, an η-factor is determined relating the J-integral to the internal energy measured along the specimen crack faces. It is shown through the finite element computation that it is justifiable to define an η-factor. With this result, it is now possible to perform tests on aluminium specimens so as to determine JIIc. © 1990 Kluwer Academic Publishers.
