| Abstract: | U-shaped multi-angle draw-bending parts were designed based on features about auto body panels in the stamping process, and a real time strain measuring device was designed. The draw-bending experiments were conducted by changing numbers of bending-angles, and law of distribution of strain was studied. The influence on spring-back by multi-angle was considered. |

| Keywords: | stamping test strain measurement multi-angle draw-bending forming springback |
