Higher Order Eigenfields in Mode II Cracks Under Elastic-Plastic Deformation

Abstract

The explicit formulation of theJ-integral and theM-integral is constructed in terms of the stress intensity factor and the higher order stress coefficients for Mode II cracks under small or large scale yielding. Furthermore, the stress intensity factor and the higher order stress coefficients as well are computed with the aid of the two-stateJ- and theM - integral, which is found to be accurate and efficient. It is found that the contribution from the higher order singularities to theJ - integral is closely related to the configuration of the plastic zone.
