elasto-viscoplastic constitutive model, Bodner-Partom, FEMAbstract
A finite element implementation of the unified elasto-viscoplastic theory of Bodner-Partom for non-linear analysis is investigated in detail. Description of the Bodner-Partom constitutive equations is presented . Proposed UVSCPL procedure has been applied into MSC.Marc system and can be introduced into wide range of different finite elements (e.g. shell, solid, truss). For the validation of the proposed FE procedure the numerical simulations are presented. Additionally, the first part of the paper gives brief characterization of the engineering applications of the Bodner-Partom constitutive equations used for the different modelling of materials.
