The Importance of the Cavitation Effective Yield Stress and the Hole Slenderness Ratio for Accurate Predictions of Ballistic Limit Velocities
Rami Masri
Abstract:Perforation and penetration mechanics research is mostly governed by experimental and numerical investigations while analytical models are less available due to the extremely complicated nature of the subject. Sufficiently thick ductile targets are perforated by rigid, nose-pointed projectiles in a ballistic process whose dominant failure mode is ductile hole enlargement. Several recent studies have shown that for perforation process by ductile hole formation, the specific cavitation energy, which reflects the… Show more
