Abstract
Steady-state dynamic fields of stress and deformation have been computed for rapid mode-l crack propagation in the mid-plane of a strip of viscoplastic strain-hardening material. Both the cases of plane stress and plane strain have been considered. The system of governing equations has been solved numerically by a finite difference method, combined with an iterative procedure in the time domain which is continued until a steady-state has been reached. The effects of viscoplastic material behavior are exhibited by comparisons with results for perfectly elastic behavior. Dynamic effects due to high crack-tip speeds have been investigated, and results for the dynamic problem formulation have been contrasted with results for the corresponding quasi-static formulation.
