| 摘 要： | 为有效测量试件中的应力、应变及应变率,Hopkinson拉伸试验(TSHB)必须作优化分析,所进行的数值模拟涉及试件与杆件等连接对于实验结果的影响.为减小上升前沿、惯性效应且使试件处于一维应力及均匀应力与应变状态,优化的试件具有一定的长度与形状要求.对于高导无氧铜,由准静态试验及不同应变率与温度的优化TSHB试验得到一...

| Abstract: | Optimization on Hopkinson tensile bar tests(HTBS) should be conducted in advance for the effective measure of stress,strain and strain rate in specimen.Numerical simulation carried out involves the effects of interconnecting linkage between specimen and bars on experimental data.To reduce the rising edge,inertia effect and to make the specimen in a one-dimensional stress and uniform stress and strain state,the optimal specimen should satisfy a few length and shape requirements.For oxygen-free high conductiv... |
