摘　　要：炸药一般会在热-力耦合刺激下经历能量吸收和累积,易引起分解甚至燃烧爆炸。此过程较复杂,为深入探究炸药的热-力耦合响应机制,围绕炸药产品和炸药晶体,通过实验分析、有限元模拟、分子动力学模拟等多种研究手段,综述了热-力耦合响应机制的相关进展。目前,聚焦炸药产品应用的研究工作,多通过实验分析、有限元模拟以及二者结合的方法展开;针对炸药晶体,围绕高温-高压耦合条件,进行热-力耦合响应机制研究工作,但与实际生产条件仍存在一定差距。在未来工作中,随着实验分析技术和各类模拟手段的持续发展,有望对炸药产品及晶体在热-力耦合刺激下,不同时间尺度、不同空间尺度的物理变化过程、化学反应过程开展更为详尽的探究,推动炸药热-力耦合响应机制的进一步深入,为实现炸药从安全性科学研究向实际应用奠定扎实的理论基础。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.
