Summary

The penetration response of tungsten-alloy long-rod penetrators into soda-lime glass targets is investigated at two impact velocities. Penetration depths were measured by flash radiography at different times during penetration. A modified experimental arrangement provided independent measurements of the residual projectile length and velocity for finite-thick glass targets. Numerical simulations using a Drucker-Prager constitutive model are compared to the experimental data and conclusions are drawn concerning the constitutive behavior of the glass.
