摘要
Abstract
The temperature field and the thermal stress field of HMX based polymer bonded explosive (PBX)during ther-mal impact process was simulated by the finite element software ANSYS based on a two-dimentional axis symmetric model. The experiment of thermal shock was carried out by using thermocouples and acoustic emission technique to measure tem-perature and thermal damage respectively.The calculated results show that thermal stress leads to the thermal damage in cooling stage,and the largest tensile stress takes place in the lateral centre of the cylindrical sample.The experiment results agree well with calculated results,indicating that thermal damage of HMX based PBX is caused by tensile stress,and the tensile strength can reflect the ability of heat shock resistance for HMX based PBX preferably.关键词
