Summary

The penetration response of tungsten-alloy long-rod penetrators into soda-lime glass targets was reported at the last Cocoa Beach meeting [1]. Numerical simulations using a Drucker-Prager constitutive model were compared to experimental data at two impact velocities: 1.25 km/s and 1.70 km/s. Preliminary values for the slope and cap of the Drucker-Prager model were selected. In the current study, a modified Drucker-Prager model is examined. Results of numerical parametric studies are compared to the experimental data to determine optimal values for the constitutive parameters. At the end, it is concluded that numerical issues may be obfuscating the mechanics.
