为了了解材料在高温下的本征动态行为，本文回顾了分离式霍普金森压杆(SHPB)测试技术，介绍了高温下工作的试件和设备的原理和局限性，并介绍了试件的几何形状。通过实验测试和有限元方法，研究了该试件在加热装置切断后到撞击器撞击之前，在与压杆接触或不接触的情况下，相对于标准圆柱体试件保持温度的能力。这种特殊的样品被用来避免高温下复杂的SHPB系统，并使事情尽可能简单。
In order to understand the intrinsic dynamic behaviour of the material at elevated temperatures, this paper reviews the split Hopkinson pressure bar (SHPB) testing technique, presents the principles and limitations of the specimen and equipment for work on the elevated temperature and then introduces geometry for the specimen. The ability of this specimen to keep its temperature relative to the standard cylindrical specimen between the cut-off of the heating device and prior to the impact of the striker, with or without contact with the pressure bars, has been studied, both by experimental tests and by finite-element methods. This particular specimen is used to avoid a complicated SHPB system at an elevated temperature and to keep things as simple as possible.
