In this dissertation, the key technologies of dynamic soft reduction for an ultrahighstrengthsteel (UHSS) have been studied in view of experiment, design, modelling and dynamic control.
本文针对超高强度钢(UHSS)动态轻压下工艺的关键技术，开展实验、设计、建模与控制方面的研究。

The FEA also indicated that the residual stress only has little effect on the overall buckling resistance of the ultrahighstrengthsteel columns.
计算结果还表明，残余应力的变化对超高强度钢材焊接工形截面轴心受压柱整体稳定承载力的影响较小。

The experimental results show that the types of crack initiation at inclusion in ultrahighstrengthsteel under tensile load depend on the sizes of inclusion and the hole around inclusion.
