Abstract

Uniaxial strain plane impact (300-1700 m/s), loading and reloading experiments carried out on SS304L are reported. The aim of these experiments was to measure the material strength properties under shock compression. Most of the experiments reported here show a viscous type elastic precursor. The experimental results are compared to numerical simulations performed using a 1D code. The input physics to the simulations are the Steinberg equation of state and Johnson-Cook strength model. This model has been previously calibrated under uniaxial stress conditions in the range ε̇ =1-5×10 3 s -1. Our experiments extended the data into the region ε̇ =10 5 -10 6 s -1. In spite of this extrapolation, there is a general agreement between simulations and experiments. However, differences in some details still exist.
