From the viewpoint of the hybridization of experiment and simulation, we examined the new technique on shape freezing property evaluation of Aluminum and Magnesium alloy sheet at room temperature. The simple V-bending test was carried out and some effects (e.g. microstructure, radius of curvature and bending angle) on shape freezing property were evaluated individually. The total amount of the elastic strain became useful evaluation guideline of the shape freezing property that is not influenced in the kind of material and forming condition. By this evaluation system which hybridized simple bending test and simple FEM simulation, the prediction of spring back error will become possible in practical manufacturing.
