An Abridged Review of Empirical Formulae for Computation of Penetration, Scabbing and Perforation Depth Under Projectile Impact

Computation of penetration, scabbing and perforation depth under projectile impact is a highly non-linear and complex phenomenon.

Description
Summary:	Computation of penetration, scabbing and perforation depth under projectile impact is a highly non-linear and complex phenomenon. There exist various formulae, mainly empirical in nature, to estimate these depths under a given scenario. However, there exist a large difference between these depths computed using available empirical formulae and those observed during actual tests. In the present study, these formulae have been revisited by considering their merits and limitations and an abridged review is presented herein for a new researcher to start research in this area. Further, various methods for computation of penetration, scabbing and perforation depth are also presented and best method to compute the penetration, scabbing and perforation depth is discussed. This study will serve the basis for first order approximate computation of these depths using various computational tools as available now a days.
