To obtain dynamic behavior of materials at very high temperature, a new experimental system of high temperature split Hopkinson pressure bar (SHPB) is investigated. The steel bars in the inside section of the furnace are replaced with relatively close acoustic impedance matched short ceramic bars. Compared to the traditional high temperature SHPB system, this system can be used under higher loading and higher experimental temperatures, and it is more convenient than the auto-assembling high temperature SHPB system. In addition, the effect of impedance mismatch is investigated by numerical simulation, which proves veracity of the results. The dynamic compressive properties of anti-hydrogen steel at high temperature up to 800 ℃ are tested by this system. Results show that the flow stress of material decreases with the increase of the temperature.

讨论和分析了当前高温分离式霍普金森压杆(SHPB)实验技术,为了获得材料在高温下可靠的动态力学性能,建立了一套在压杆和试件之间添加隔热陶瓷短杆的高温SHPB实验系统。相比于传统接触式高温SHPB方案,该系统可以使用在更高的冲击载荷和温度下,与机械对杆方案相比,实验装置及其控制要简便许多。结合有限元模拟,对陶瓷短杆及温度场对压杆中应力波传播的影响进行了相应的评估,并利用这套实验系统得到了800 ℃下HR2抗氢钢的动态压缩应力-应变曲线。

讨论和分析了当前高温分离式霍普金森压杆(SHPB)实验技术,为了获得材料在高温下可靠的动态力学性能,建立了一套在压杆和试件之间添加隔热陶瓷短杆的高温SHPB实验系统。相比于传统接触式高温SHPB方案,该系统可以使用在更高的冲击载荷和温度下,与机械对杆方案相比,实验装置及其控制要简便许多。结合有限元模拟,对陶瓷短杆及温度场对压杆中应力波传播的影响进行了相应的评估,并利用这套实验系统得到了800 ℃下HR2抗氢钢的动态压缩应力-应变曲线。

To obtain dynamic behavior of materials at very high temperature, a new experimental system of high temperature split Hopkinson pressure bar (SHPB) is investigated. The steel bars in the inside section of the furnace are replaced with relatively close acoustic impedance matched short ceramic bars. Compared to the traditional high temperature SHPB system, this system can be used under higher loading and higher experimental temperatures, and it is more convenient than the auto-assembling high temperature SHPB system. In addition, the effect of impedance mismatch is investigated by numerical simulation, which proves veracity of the results. The dynamic compressive properties of anti-hydrogen steel at high temperature up to 800 ℃ are tested by this system. Results show that the flow stress of material decreases with the increase of the temperature.
