Testing of the Johnson-Cook material model VPJC in EUROPLEXUS

Abstract

This document presents some numerical tests for the verification of the Johnson-Cook material model(VPJC) recently introduced in the EUROPLEXUS code (EPX).EUROPLEXUS [1] is a computer code jointly developed by the French Commissariat ́a l’EnergieAtomique (CEA DMT Saclay) and by EC-JRC. The code application domain is the numerical simula-tion of fast transient phenomena such as explosions, crashes and impacts in complex three-dimensional fluid-structure systems. The Cast3m [2] software from CEA is used as a pre-processor to EPX when it is necessary togenerate complex meshes.
