ANALYTICAL VERSIONS OF PENETRATION PROCESSES

Abstract

In the interest of obtaining a comprehensive view of the penetration of bodies into solid plates some of the more prominent theoretical relations used to describe penetration processes are outlined and correlated. The velocity ranges to which these relations apply and the assumptions used in the analytical developments are summarized. Elastic behavior processes in impact are first discussed to establish lower bounds on the impact velocity for the formation of a crater. Various analytical representations of crater formation processes are summarized and the advantages of the theory of constant dynamic flow pressure are demonstrated by calculated results which agree well with experimental penetration data from several sources. The hydrodynamic theory of penetration and Opik's theory of penetration are discussed in relation to these conclusions on crater formation.
