Anisotropy is an important parameter to be considered in modelling of bending processes. In practice, bending of sheet metals perpendicular to the rolling direction yields more desirable bend profiles; this is especially important for sheet metals of high strength. Theoretical analysis has been made and a process constant specifying the plane bending of anisotropic sheets defined. It was found that the effect of anisotropy on material thinning of a bend is small but has a large effect on the bending moment. Since the springback is proportional to the bending moment, the anisotropic effect on springback is considerable. The predicted results were in good agreement with the experiment results using austenitic stainless steel and aluminum alloy specimens.
