炸药热-力耦合响应机制研究进展OA北大核心CSTPCD

The temperature-force coupling response mechanism has been a scientific problem in the field of explosive safety.The response progress of explosives under temperature-force coupling actions is complicated,which is easy to cause decomposition and even combustion explosion of explosives after energy absorption and accumulation.In order to further explore the thermo-me-chanical coupling response mechanism of explosives,the related progress for thermo-mechanical coupling response mechanism of ex-plosive products and explosive crystals was reviewed by means of experimental analysis,finite element simulation,molecular dy-namics simulation and other research methods.Presently,the coupling response mechanism of explosive products was carried out via experimental analysis,numerical simulation or both two methods.On the other hands,the coupling response mechanism of explosive crystals was carried out under the high temperature-high pressure coupling conditions,which is different from the actual producing conditions.With the continuous development of experimental analysis technology and simulation methods,more detailed physical change process and chemical reaction process of explosive products and crystals under the thermal-mechanical coupling action will be explored at different time scales and different spatial scales,which lay a solid theoretical foundation for the realization of explo-sives from safety research to practical application.
