Notes:
In the deep drawing of cups, the earing defect is caused primarily by planar anisotropy inthe sheet. In order to obtain the optimal products in deep drawing process, blank shape is a veryimportant formability factor. In this study, the finite element method was used to investigate the cupheight and forming force of the cylindrical cup drawing process. A finite element analysis was alsoutilized to acquire the designed profile of the drawn products, a reverse forming method forobtaining the initial blank’s shape according to the forward cylindrical cup drawing simulation isproposed. The design of initial blank’s shape is also confirmed to obtain the designed profile ofdrawn cups. The influences of the blank’s shape on the height of product, the forming force, theeffective stress and the effective strain were also examined
