| 摘 要： | 采用入射波整形技术对Al203陶瓷进行了分离式霍普金森压杆(SHPB)动态压缩试验。通过合理设计整形器尺寸和子弹初速，获得了较为理想的入射波。试验结果表明：入射波整形技术可以有效地研究脆性材料的恒应变率变形行为；而入射波整形技术结合直接测量应变方法可以准确地测定高强度脆性材料在高应变率下的应力一应变曲线。

| Abstract: | Split Hopkinson pressure bar(SHPB) dynamic compression tests were conducted for Al2O3 ceramics by employing the novel pulse shaping technique.Expected incident pulse was obtained through reasonable design of the pulse shaper size and the initial velocity of striker bar.It is shown that the pulse shaping technique is fairly available to study the dynamic behavior of brittle materials under the condition of constant strain rates;and such technique combined with direct measurement of sample strain can be used ... |
