The Impacting Dynamic Response of Energetic Materials PTFE/Al

Abstract

PTFE/Al is the most representative of a new class of advanced energetic materials. In order to study the dynamics response under impact, carrying out numerical simulation for the pressure changes and plastic deformation which were generated from PTFE/Al with a metal shell penetrating aluminum alloy target by using LSDYNA. By analyzing the pressure on the observation point, flash and unit deformation characteristic, summarizing Energetic Materials PTFE/Al impact dynamic response. Combining the literature experimental results verify that the simulation is reasonable.
