Abstract

A major part of this work was to establish a new data base for AISI type 316H austenitic stainless steel, related to its sensitivity to strain rate history, and evaluate the observed mechanical response using one of the many modern approaches to constitutive modelling. The phenomenological description of the material was a series of interrupted tensile loading with strain rate change from quasi-static to dynamic. These data clearly showed that the material strength, although strain rate sensitive, is not affected by the strain rate history, indicating that a mechanical equation of state could be applied. The Bodner-Partom constitutive theory is first calibrated by the monotonic stress - strain curves collected at steady constant strain rates, then used to predict the response under various types of interrupted strain rate change tests.
