✦ Synopsis

We developed penetration equations for rigid spherical-nose rods that penetrate ductile metal targets. The spherical cavity-expansion approximation and incompressible and compressible elastic-perfectly plastic constitutive idealizations simplified the target analyses, so we obtained closed-form penetration equations. We compared predictions from our models with previously published penetration data and results from Lagrangian and Eulerian wavecodes.

We present penetration equations for rigid, spherical-nosed rods that penetrate 6061-T651 aluminum targets. The penetration models use the spherical cavity-expansion approximation and constitutive equations for the target that include strain hardening and strain-rate sensitivity. We obtained closed-
