Fracture under elastic-plastic condition is a topic of current interest         to the fracture mechanics community as crack propagation in engineering         metals involves considerable plastic deformation.  The problem of               initiation and subsequent growth of the crack is made more complex under        combined loading where both the in-plane tensile mode (mode I) and the          out-of-plane tearing mode (mode III) occur.  The research program               analyzes the case of mixed mode loading of cracks in elastic-plastic            materials.  The method of solution involves a differential equation             subject to the mixed boundary conditions.  The approach yields free             parameters to be evaluated numerically using finite elements.
