Abstract

According to different type tactical missile warhead, structure of which was equivalent to charges covered by single-shell or double-shell. The shock initiation response of cast TNT charges, covered by single-shell and double-shell casing impacted by hypervelocity fragment was investigated using non-linear dynamics software AUTODYN. Results shows that in hypervelocity impact conditions, the first layer of double-shell charge imposed severe breaking effect to fragment and generated debris clouds, then the surface impulse density of fragment to rear shell reduces significantly. When impacted by same mass, shape, velocity projectile, deflagration will occur for single shell charges, however, no deflagration can be observed for double shell charges with the same thickness.
