Simulation on Influence of Two-Stage Warhead Penetration at Different Obliquity Angles

In order to study the influence of the Two-Stage warhead penetration with obliquity angle, used finite software LS-DYNA to simulate the process of the two-stage warhead attacking double equivalence target with different obliquity angles, analyzed the influence of residual velocity, shell and inner structure strength of the two stage warhead at angles. The results show that when the obliquity angle increase, it has little affect to residual velocity, but the strength of last stage warhead shell and inner structure facing austere influence and the deformation aggravate.
