Abstract
We present the numerical algorithm for the model for high-strain rate deformation in hyperelastic- viscoplastic materials based on a fully conservative Eulerian formulation by Plohr and Sharp. We use a hyperelastic equation of state and the modi¯ed Steinberg and Lund's rate dependent plasticity model for plasticity. A two-dimensional approximate Riemann solver is constructed in an unsplit manner to resolve the complex wave structure and com-bined with the second order TVD °ux. Numerical results are also presented.
