Effect of Process Variables and Material Properties on the Springback Behavior of 2D-Draw Bending Parts 950692

A bending and springback analysis method for 2D-draw bending parts has been developed based on a new mathematical model. The main feature of the new model is described and the analysis results obtained from this model are compared with those from other methods. These results show consistent springback behavior for the selected cases. Roles of blankholder force and friction are investigated using the new method, as well as the effect of material properties on springback behavior, e.g., strain hardening index, Young's modulus, plastic anisotropy, etc. The trends are illustrated graphically and some conclusions are drawn based on the analysis.
