采用新近发展起来的拉伸式Ｈｏｐｋｉｎｓｏｎ冲击装置（ＳＨＴＢ），成功地实现了对岩石试样的动态直接拉伸加载。利用圆柱形拉伸强度试样和切口圆柱拉伸断裂试样，并结合静态拉伸实验设备ＭＴＳ材料试验机，进行了岩石的动态拉伸强度、动态拉伸断裂、静态拉伸强度、静态拉伸断裂共４种情况下的拉伸破坏实验，并将这４种实验条件下的拉伸破坏试样沿其纵剖面剖开，利用光学显微镜观察岩石在其纵剖面上的破坏特征。观察表明，岩石拉伸破坏所消耗的能量与岩石破坏时所形成的内部损伤有着十分密切的联系。
Using the newly developed tensile Hopkinson impact device (SHTB), dynamic direct tensile loading of rock samples has been successfully achieved. The dynamic tensile strength, dynamic tensile fracture, static tensile strength and static tensile strength of the rock were measured by using cylindrical tensile specimen and notch cylindrical tensile specimen, combined with the static tensile test equipment MTS material testing machine Tensile failure tests were carried out under four different conditions. Tensile failure specimens under the four experimental conditions were cut along the longitudinal section and the damage characteristics of the rock on its longitudinal section were observed by light microscopy. The observation shows that the energy consumed by tensile failure of rock is closely related to the internal damage caused by rock failure.
