000014257 520__ $$2eng$$aIn this work we investigate the interplay between material defects and flow localization in elastoplastic bars subjected to dynamic tension. For that task, we have developed a 1D finite difference scheme within a large deformation framework in which the material is modelled using rate-dependent J2 plasticity. A perturbation of the initial yield stress is introduced in each node of the finite difference mesh to model localized material flaws. Our results indicate that wave propagation phenomena control, to a large extent, flow localization in elastoplastic specimens subjected to impact tensile loading.
