Containing Can Fragment The Simulated Warhead Detonation Mechanism

In this dissertation, a design program of explosive energetic fragment with upper efficiency damage to warhead cabin of cruise missile is established by carefully analyze to the framework and the materials of warhead cabin. At the same time, we have made researches in two aspects: mechanical damage and detonate damage according to the process which the fragments penetrated the warhead cabin of the cruise missile. In the field of mechanical penetrating damage, we found the ultimate velocity when the fragments penetrated differ-thickness targets according to numerical simulation. In the field of detonate damage, we found the common rules that the warhead detonated by fragments also according to numerical simulation. The design program of energetic fragment and the results of numerical simulation had been validated by a series of experiments.In exploring the process that warhead cabin attacked by explosive energetic fragment, we analyzed the results of numerical simulation and phenomena of experiments, sum up the foregoing results and then got a new hypothesis about the fragments' shock wave inducted the hotspot when the energetic fragment burst..
