The residual stresses in the blank after forming are the main cause for the subsequent springback in a sheet forming operation. The accuracy of the predicted springback in a Finite Element simulation of the forming operation is very much determined by the quality of the material modeling. Those parts of the workpiece, which in particular contribute to the global springback, have usually been su...

Abstract As the first study in field regarding CB, this paper investigates implications of interchanging between RDB and CB through manufacturing bends with various angles difference two methods form springback, cross section compression widening, shape wall thinning/thickening. The experiments conducted consists aluminum alloy 6060-T4 round tubes 60 mm diameter 3 thickness, bent around 222 rad...
