Abstract
To investigate the role of the hydrostatic stress on failure, some static a nd dynamic tensile tests on mild steel axisymmetric notched specimens are d escribed in this paper. Finite-Element results and experimental data indica te 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 tr iaxiality levels is explored. (C) 1999 Elsevier Science Ltd.
