大型薄板冲压成形中的起皱现象是多种多样的 ,通过对剪应力下的起皱进行实验研究 ,提出了剪应力起皱实验方法 ,探讨了剪应力起皱的过程 ,及材料性能、起皱区域尺寸等主要因素对剪应力起皱的影响
The phenomenon of wrinkling in large-scale sheet metal stamping is diversified. Through the experimental research on the wrinkling under shear stress, the paper presents the experimental method of wrinkle wrinkling, and discusses the process of shear stress wrinkling and the material properties. The effect of main factors such as wrinkle area size on shear stress wrinkling
