When impact compression test is exerted, the pulse shaper has been used to regulate the incidence wave, so that the stress gradient will not be significantly high and the results is acceptable.
在进行冲击压缩实验时采用波形整形器调整入射脉冲，从而使得试件内的应力梯度不致过大，取得了较好的效果。
The results show that the high stress is main concentred on the wall of the ladle, and high thermal stress appears at the ladle bottom with high thermal gradient.
结果表明，高应力区主要集中在钢液罐罐壁，在罐底温度梯度较大的部分会产生较大的热应力。
Residual stress distribution of FSW has high gradient, which makes the conventional strain gauge hole drilling method unsuitable.
