【 摘 要 】

This paper analysed the local thickening of tailored blanks using Finite Element Method. In this process, local thickening was produced at the centre of the sheet by beading and compression. In the beading process, the sheet is beaded freely and no change in thickness occurs. The beaded area was then compressed with no change in width to form a thicker portion at the centre of the sheet. The amount of thickening formed increases with the increase of the beading height. However for beading height 8 mm folding occurred. These processes do not involve joining and hence stress concentration by the change of thickness can be prevented.
