摘要
为研究岩石在高应变率作用下的微观损伤特征，用三轴ＳＨＰＢ装置对混合花岗岩和磁铁矿矿石进行高速冲击，用光学显微镜和扫描电镜观察矿物颗粒的受损状态。
In order to study microscopic damaged specifics of rock under high strain rate, some samples of migmatitic granite and magnetite ore have been impacted in high velocity through three axes SHPB (Split Hopkinson Pressure Bar) experimental apparatus, and the damaged states of particles in rocks have been observed through a polarizing microscope and a scanning electronic microscope. The microscopic damaged specifics of rock is shown in this paper.
