Metal plastic deforming process is a kind of quite complex and largeelastic-plasticdeformation process.
金属塑性加工的变形过程是一个非常复杂的弹塑性大变形过程。

The finite strip method in structural analysis has been extended, and elastic-plasticlargedeformation spline finite strip method based on the Updated-Lagrange method (U.
拓展了结构分析有限条法，基于固体力学有限形变理论的更新拉格朗日法（U 。

We found: the samples experience elastic and plasticdeformation processes before fracture, and the elastic strain is very large, it is about 2%.
