Research on penetration effect of reactive fragment striking to moderately thick al-alloy targets

摘要：

　　The penetration effect of reactive fragment striking to moderately thick al-alloy targets was studied.An experiment equipment was designed to study the penetration of single reactive fragment at different impacting velocity, and the penetration process of reactive fragment striking to al-alloy targets was simulated by means of the finite element analysis software AUTODYN-2D.It can be discovered that Al/PTFE reactive fragments have double damage effect with kinetic energy and chemical energy under the state of high velocity.The fragment ignites and releases energy in 1346-1645m/s impacting speed, and 3.41-6.51mm holes form on the 20mm thick aluminum alloy target.The numerical simulation results based on the experiment were tally well with the experiment results.
