The Study of Forward Shaped Charge Structure for Tandem Warhead Based on LS-DYNA

A small length-diameter ratio structure with changed conical angle was designed for forward shaped charge of tandem warhead. Using the multi-material ALE algorithm, the jet formation process of cone charge and the designed charge was numerically simulated based on a finite element program LS-DYNA. S...

Zusammenfassung:A small length-diameter ratio structure with changed conical angle was designed for forward shaped charge of tandem warhead. Using the multi-material ALE algorithm, the jet formation process of cone charge and the designed charge was numerically simulated based on a finite element program LS-DYNA. Simulation results show that the latter can form a jet which can better meet the requirement of forward shaped charge for tandem warhead.
