摘要：

To investigate the role of the hydrostatic stress on failure, some static and dynamic tensile tests on mild steel axisymmetric notched specimens are described in this paper. Finite-Element results and experimental data indicate that the failure site, for specimens having a small notch radius, occurs in regions of low triaxiality. Comparisons are made between Finite-Element and Bridgman analyses. The influence of some material parameters on the triaxiality levels is explored. (C) 1999 Elsevier Science Ltd.
