Theoretic research on the springback of sheet metal bending

LI Ou\|qing LIANG Qing\|wei (Alcatel\|Shanghai Bell Co.Ltd.Shanghai 201206) WU Dian\|liang (Xi'an Jiaotong University,Shanghai 710049)  
Based on the supposition of plane strain and von Mises yield criterion,neglecting the thinning in the bending area,a model for calculating the springback and a formula for calculating the minimal bending radius during sheet metal bending.The the numeric method for solve the problem of springback and fracture during general blank bending which has different bending angle along the knife\|edge of the punch.
