Study on mechanical properties and damage characteristics of booster explosives under static compression

  • 摘要: 为研究聚黑-14C(JH-14C)传爆药静态压缩力学性能及损伤特性,开展准静态压缩实验,获得了不同应变率下的应力-应变曲线,建立了描述不同应变率下JH-14C力学行为的非线性本构模型;利用扫描电镜(SEM)对回收试样进行细微形貌观测,获得了准静态压缩JH-14C损伤特性的表征。结果表明:JH-14C压缩强度随应变率的升高而提高;实验与计算结果对照验证了本构模型的有效性;准静态压缩实验中,JH-14C主要损伤模式为脱湿和穿晶断裂。
