Open publisher page 0 citations

Abstract

Base on the calculation software of 3D LS DYNA dynamics of finite element method,the model of shaped charge jet penetrating concrete target reinforced with steel fiber was established,and formation and penetration process of metal jet were studied by numerical simulation,and the comparison with X rays of jet formation was made. The displacement time curve of jet penetration into target was described,and the accuracy of simulation results was verified by penetration test.
