The aim of the paper is to propose an FE procedure for static and dynamic nonlinear analysis including elasto-viscoplastic constitutive equations of the Bodner-Partom model. Basic equations of the constitutive model are given with the flow graph used in the FE procedure. The proposed procedure has been applied in the MSC.Marc commercial system with a user-defined UVSCPL subroutine that enables application to a wide range of varied finite elements. A number of simple problems of static and dynamic analysis are presented to show the accuracy of this approach. The numerical simulations are compared with experiments to validate the proposed FE procedure.
