Abstract

This paper presents finite element modeling procedure for rate-dependent elastic-plastic nonhomogeneous carbon steel plates subjected to dynamic loads. The steel plate consists of two ductile materials. We utilize a modified rule of mixture and linear strain-rate dependence to derive constitutive relations which are then implemented in ABAQUS/Explicit through user subroutine. Validation of the developed procedure is partially made with Steel 1018. Comparative numerical study is done between Steel 1018 and the nonhomogeneous plate. Displacements, stresses and relevant energy terms are calculated and compared for various sets of material configurations. © Published under licence by IOP Publishing Ltd.
