Summary
We present the results of 2D lagrangian hydrodynamic simulations of cylinder impact experiments using a recently developed model for rate-dependent elastic-plastic flow. This model, which takes advantage of empirical scaling relations in terms of melting temperature and shear modulus is consistent with the very high strain-rate behavior deduced from overdriven shock data is in good agreement with the temperature and density dependence of the flow stress where known. Calculations for uranium and copper are discussed. 12 refs., 3 figs., 2 tabs.
