SCALING OF THE SHAPED CHARGE JET BREAK-UP TIME: A LINER THICKNESS EFFECT OBSERVED AND EXPLAINED

摘要

Experimental data and use of Vpl-based break-up models in three different shaped charge jet formation analytical computer codes reveal that Vpl - a measure relating a local variation in jet kinetic energy to local material strength during jet elongation - has an inverse dependence on liner thickness. This dependence appears to be affected by initial coupling of the explosive's detonation into the liner wherein the coupled energy changes the liner material structure and properties.
