Most sheet metal operations involve some kind of bending. To avoid unwanted spring back after bending, which causes undesirable effects in final product, as in stretch forming, tension is applied simultaneously with bending. Since the tension plays major role and strongly affects the bending moment, analysis of sheet metal bending under tension is important. In this study, an analytical model has been developed for sheet metal subjected to plane strain bending under tension. The model has been used to describe the effect of tension force on the bending moment in a linear elastic-work hardening sheet material. Then, the bending moment versus tension has been plotted. Finally influence of punch radius and material parameter on the shape of moment-tension curve will be discussed.
