✦ Synopsis

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 q-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 q-factor. With this result, it is now possible to perform tests on aluminium specimens so as to determine Jlxc.

A series of studies which demonstrate the potential of a proposed mode I1 fracture specimen are reported. First, previously obtained photoelastie results&31 are reviewed so that this paper will be self-contained. Then, a finite element analysis is presented in order not only to corroborate the exper

## Several theories have been proposed for the failure of metals, as well as for the angle of crack propagation in mixed mode loading. In order to demonstrate the validity of these theories, the majority of tests have been carried out with an oblique crack placed in a uniaxial stress field. Better
