One of the most sensitive features of sheet metal forming processes is the elastic recovery during unloading, called spring-back, which leads to some geometric changes in the product. This phenomenon will affect bend angle and bend curvature, and can be influenced by various factors. In this research, the effects of anisotropy i.e., the rolling direction of 0° , 45° & 90° of ultra low carbon steel Interstitial Free (IF) Steel in V- bending with a punch corner radii of 7.5mm, were studied by experiments and numerical simulations. Comparison between the experimental and the finite element simulation results are also presented and found to be in close agreement.
