Abstract

Steady-state dynamic fields of stress and deformation have been computed for rapid crack propagation in the mid-plane of a thick strip of a viscoplastic work-hardening material. The faces of the strip are subjected to prescribed anti-plane displacements. The system of governing equations has been solved numerically by a finite difference method with an iterative procedure in the time domain which is continued until a steady-state has been reached. The effects of viscoplastic material behavior have been exhibited by comparisons with the results for the corresponding perfectly elastic problem. Dynamic effects due to high crack-tip speeds have been investigated and dynamic results have been compared with results obtained on the basis of a quasi-static problem formulation.
