An efficient numerical implementation of the Bodner-Partom model in the EPIC-2 code

The two main objectives of this paper are; (1) to present an efficient numerical scheme based on an iterative radial corrector method for solving the Bodner-Partom equations in the explicit finite element code, EPIC-2, and (2) to compare the EPIC-2 results obtained using two different viscoplastic constitutive models. Two distinctly different viscoplastic models, Johnson-Cook and Bodner-Partom, were considered. Both models predicted similar solutions in most problems.
