PBX explosive is the main charge of modern weapons, so its mechanical behavior determines the survival ability of weapons. To study the dynamic behavior of PBX explosive, a series of split Hopkinson pressure bar (SHPB) tests for PBX explosive have been carried out. With combination of the semiconductor strain gauge and quartz crystal transducer, the validity of the experimental data was obtained. In addition, the stress equilibrium of the specimen and constant strain rate loading were realized experimentally using wave shaping technique. The stress-strain curves of PBX explosive under different strain rates (90~410 s-1) were acquired. According to the variations of the dynamic modulus, failure strength and failure strain with strain rate, a constitutive model of the PBX explosive under uniaxial compression was proposed. The fitted curves derived from the developed model agree well with the experimental results.

PBX炸药作为现代武器的主装药,它的力学行为决定着武器的生存能力。为了研究PBX炸药的动态力学特性,采用分离式霍普金森压杆(Split Hopkinson Pressure Bar,SHPB)作为加载手段,结合半导体应变片测试技术和压电晶体监测技术,保证了实验数据的有效性。利用SHPB加载波整形技术,实现了材料两端应力平衡和常应变率加载,得到了不同应变率(90~410 s-1)下材料的应力-应变曲线。根据材料的模量、破坏强度和破坏应变随应变率的变化规律,采用粘性修正的Sargin模型,得到了该PBX炸药在单轴压缩下的唯象本构模型,模拟结果与实验曲线符合较好。

PBX炸药作为现代武器的主装药,它的力学行为决定着武器的生存能力。为了研究PBX炸药的动态力学特性,采用分离式霍普金森压杆(Split Hopkinson Pressure Bar,SHPB)作为加载手段,结合半导体应变片测试技术和压电晶体监测技术,保证了实验数据的有效性。利用SHPB加载波整形技术,实现了材料两端应力平衡和常应变率加载,得到了不同应变率(90~410 s-1)下材料的应力-应变曲线。根据材料的模量、破坏强度和破坏应变随应变率的变化规律,采用粘性修正的Sargin模型,得到了该PBX炸药在单轴压缩下的唯象本构模型,模拟结果与实验曲线符合较好。

PBX explosive is the main charge of modern weapons, so its mechanical behavior determines the survival ability of weapons. To study the dynamic behavior of PBX explosive, a series of split Hopkinson pressure bar (SHPB) tests for PBX explosive have been carried out. With combination of the semiconductor strain gauge and quartz crystal transducer, the validity of the experimental data was obtained. In addition, the stress equilibrium of the specimen and constant strain rate loading were realized experimentally using wave shaping technique. The stress-strain curves of PBX explosive under different strain rates (90~410 s-1) were acquired. According to the variations of the dynamic modulus, failure strength and failure strain with strain rate, a constitutive model of the PBX explosive under uniaxial compression was proposed. The fitted curves derived from the developed model agree well with the experimental results.
