Solidification Simulation of Melt-cast Explosive under Pressurization

摘要

The flow field, temperature field and stress field on the melt-cast explosive process have been studied by using software of Procast combined with experimental method, from which the thermodynamic characteristics of the explosives melt-casting process has been researched. The simulation results show that the charge shrinkage, cracks and pore formation could be effectively reduced by adjusting the temperature and pressure. The simulation results could be used for the optimization of casting processes, thereby improved the safety performance of Melt-cast explosive.
