Abstract
In this paper, the penetration process of ogive-nose
projectiles into the semi-infinite concrete target is investigated by the
dimensional analysis method and FEM simulation. With the dimensional
analysis, main non-dimensional parameters which control the penetration
depth are obtained with some reasonable hypothesis. Then, a new
semi-empirical equation is present based on the original work of Forrestal
et al., has only two non-dimensional combined variables with definite physical
meanings. To verify this equation, prediction results are compared with
experiments in a wide variation region of velocity. Then, a commercial FEM
code, LS-DYNA, is used to simulate the complex penetration process, that
also show the novel semi-empirical equation is reasonable for determining
the penetration depth in a concrete target.
