The development of a finite elements based springback compensation tool for sheet metal products [PDF]
, 2005 Springback is a major problem in the deep drawing process. When the tools are released after the forming stage, the product springs back due to the action of internal stresses. In many cases the shape deviation is too large and springback compensation is
