摘要

摘要: 通过扫描电镜，对三种含能材料在不同应变率压缩条件下回收的试样断面进行了细观观察，得到了三种含能材料的细观破坏特征，并对其破坏机理进行了分析。同时结合高聚物粘结炸药（PBX炸药）和压装B炸药组分的比较，分析了两种炸药在高应变率条件下的不同破坏模式。

Abstract: The fractural surfaces of the compression tested specimens have been observed by scanning electron microscope (SEM). Microstructure fractural characteristics of three energetic materials under compressive loading at different strain rates are obtained. Based on the material composition, the fractural mechanisms of the PBX and Comp.B under the loading are discussed, respectively, which attempts to explain differences of the fractural characteristics between the two explosives.
