Abstract
The penetration and cratering process for non-deforming projectiles impacting ductile targets is modeled analytically on the basis of an aerodynamic analogy involving a rigid-plastic 'atmosphere'. A set of coefficients is determined which can be used to predict the behaviour of cylindrical projectiles having tips that are either purely conical or comprised of two conical sections. Comparisons made with experiment show good agreement for a variety of projectile/target combinations and demonstrate that the model can be used to optimize the design of a penetrator for a specific velocity range and target material.
