000021536 520__ $$2eng$$aA finite volume method is used and extended for the numerical simulation of impacts on elastic-viscoplastic solids with bidimensional curvilinear structured meshes. The formulation is based on the flux-difference splitting method [1], has second order accuracy through flux limiters, embeds the corner transport upwind method, and uses the second order accurate Strang splitting method to handle the right hand side of the system of balance laws. The approach is here derived with a Chaboche-type [2] elastic-viscoplastic solid within the small strain framework, and is illustrated on a problem of impact on a heterogeneous volume containing an inclusion. A comparison is performed with a finite element solution obtained with the finite element code Cast3M [3].
