摘要
Abstract
The LS‐DYNA program to the problem of shaped charge numerical simulation is an economic and effective way .To solve the problems of low efficiency ,difficult of coupling and computing in the simulation with simple 3D‐Fluid‐Structure Interaction(FSI) method ,2D/3D pure ALE method is proposed .With the LS‐DYNA program ,above methods are used to simulate and compare the process of jet forming and penetrating target respectively .It proves that the pure ALE method is more fluent and stable ,the results coincide well with the experimental results .Under the same condition ,the 2D pure ALE method has a higher accuracy ,the computational efficiency is greatly improved ,which makes up for the fault that it can only use 3D method for simulation in the past .关键词
