Nettet27. jul. 2011 · This article presents a computational constitutive model for glass subjected to large strains, high strain rates and high pressures. The model has similarities to a previously developed model for brittle materials by Johnson, Holmquist and Beissel (JHB model), but there are significant differences. This new glass model provides a ... NettetG. R. Johnson, W. Cook Published 2024 Materials Science This paper presents a constitutive model and data for materials subjected td large strains, high strain rates and high temperatures. The basic form of the model is well suited for computations because it uses variables which are readily available in most of the applicable computer codes.

In this study, tensile tests of 304 and 316 austenitic stainless steels (ASS) at various strain rates were performed to investigate the strain rate effect on tensile properties. It is shown that the strain rate effect on stress depends not only on the strain rate but also on the plastic strain level.
