The Effect of Explosive Material on the Formation of Explosively Formed Penetrator Qinshu Miao1,2, a, Xiaoming Wang1,b, Wenbin Li1,c, Weibing Li1, d, Yu Zheng1,e 1ZNDY of Ministerial Key Laboratory Nanjing University of Science and Technology, Nanjing 210094, China 2 Unit 63961 of PLA, Beijing 100012, China amqslxf@163.com, bwangxm@mail.njust.edu.cn, cacnet@mail.njust.edu.cn, dnjustlwb@163.com, ezhengyu9989@yahoo.com.cn Key words: Explosive Material; Explosively Formed Penetrator(EFP); Material Character; Numerical Simulation Abstract: In order to research the effect of explosive material on the formation of EFP, this paper studies the effect of five different explosive materials, PETN, SEP, TNT, PE4BOOSTER and 8701, on forming EFP, using ANSYS/LS-DYNA simulation software.
Five explosive materials form typical explosively formed penetrator, from PETN to 8701, the length of penetrator head long rod gradually become longer apparently, velocity and length to diameter ratio are increased. 
The EFP formed influence factors are density, detonation velocity, detonation pressure, explosion heat of explosive materials, the following are the analysis of each EFP formed influence factor of different explosive materials, the influence law of EFP formed that depend on explosives material parameters which obtain explosive density, detonation velocity and detonation pressure is researched.
From the analysis that the EFP formed influence on detonation pressure of different explosive materials, the fitting curve that EFP velocity and length to diameter ratio with detonation pressure is obtained.
