Abstract

Recent usage of SHOCK WAVEs in industry necessitates a large effort to increase the accuracy and ability of the numerical simulations of shock dynamics. To fulfill this requirement, many models to predict the behavior of materials under dynamic loading have been presented by researchers. There have been many efforts to construct a model, which can explain this behavior accurately for a wide range of problems. Unfortunately such attempts have failed because of the nonlinear nature of the underlay processes. However, there are plenty of models to express the behavior of materials in a specific range. In this paper we compare two widely used models, namelg Johnson-Cook and Steinberg models. The results of numerical simulations show that both models provide good results for a wide range of shock loading. However, Steinberg model is superior in problems, which encounter large strain rates.
