摘要:
利用分离式霍普金森压杆（SHPB）对一种RDX基PBX炸药进行了高应变率加载试验，得到了其在不同应变率（300~1 200 s－1）范围内的力学性能，并用扫描电子显微镜（SEM）对回收样品进行了微观分析。结果表明：材料的力学性能和损伤均具有明显的应变率效应。采用含损伤的ZWT非线性黏弹性本构模型，对试验数据进行了拟合，拟合曲线和试验曲线吻合良好。
Abstract:
Mechanical behaviors of one RDXbased PBX explosive were investigated experimentally by split Hopkinson pressure bars (SHPB) at different strainrates (ranged from 300 to 1200 s－1) respectively. The recovered specimens were analyzed by scanning electron microscope (SEM).The results show that the mechanical behaviors and the damage of the RDX based PBX explosive are obviously ratedependent. The constitutive model of damagemodified ZWT nonlinear viscoelastic was fitted by using the tress and train data, which is in accord with the experiment curves well.
