✦ Synopsis

Recent experimental measurements show that eroding long-rod penetration velocity is a linear function of impact velocity over a very wide range of impact velocities and for an interesting range of rod-target material combinations. These experiments all show that U ¼ a+bV, where U and V are the penetration and impact velocity, respectively, and ''a'' and ''b'' are constants for given projectile and target materials. Numerical simulations also show that U ¼ a+bV. The accumulation of these results suggests that a linear relationship between penetration and impact velocity may be fundamental over a very large range of impact velocities. A linear relationship between penetration and impact velocity has a number of implications. Some implications of this result for the Tate-Alekseevskii model are briefly examined in this paper.
