Numerical Simulation on Jet Formation of a New Star Shaped Liner

A new star cone-shaped liner was investigated.It is a shape charges with star-shaped liner by changing charge structure based on wedge-shaped liner.The liner is constitute of several symmetrical cuneiform liners and concentration at their one end.A nonlinear finite element software was used to complete the numerical simulation of the star liner forming jet under explosion load.The result shows that the new liner can form jet and achieve expected result.The research result can provide a new selection for new style shaped charge warhead and has a feasible future in the field of anti-armor warhead.
