Numerical Simulation of Steel Target Penetration by Shaped Charge Distended Jet with a High-Polymer Liner

This study investigates the characteristics of shaped charge jet formed with a high-polymer (PTFE) liner, as well as its penetration capabilities, by theoretical, experimental, and numerical methods. This work presents a viscoplastic model and equation of compressible fluid to describe the jet cohes...
