| 摘 要： | 利用万能材料试验机对一种高聚物粘结炸药（简称PBX炸药）和压装B炸药进行了准静态压缩实验，得到了两种炸药在不同应变率下的应力应变曲线。通过两种炸药在不同应变率下力学性能的研究，建立了两种炸药含应变率效应的本构方程。结果表明，建立的本构方程能较好地描述两种炸药在弹性阶段和强化阶段的力学性能。

| Abstract: | Compressive behaviors of a polymer bonded explosive (PBX) and pressed Comp.B have been tested by means of a hydraulic material test machine at different strain-rates.Stress-strain curves of the materials at different strain rates have been obtained in this paper.According to the study on the mechanical behaviors of the two kinds of explosives at different strain-rates,the constitutive relations have been derived,which agree well with the experimental data from quasi-static tests during the linear elastic and strain-hardening stages of the stress-strain curves. |
