Prevention of Wrinkling in Shrink Flanging of Ultra-High Strength Steel Sheets Using Gradually Contacting Punch

To prevent the occurrence of wrinkling in the shrink flanging of ultra-high strength steel sheets, a gradually contacting punch was developed. Compressive stress around the convex corner of the sheet in shrink flanging was reduced by gradually bending the edge from the center to the outside of the s...
