Computational modelling of split hopkinson test performed on confined concrete

摘要

This paper presents first results obtained with a new mixed damage and plasticity constitutive behaviour for the modeling of concrete under fast dynamical loading. The implementation has been carried out in the Lagranginafinite element code DYNA3D. In order to validate the numerical approach, simulations of split Hopkinson test are carried out, comparisons of response obtained with the proposed model and with two DYNA3D's ones are presented.
