Experiment Study on Shape Defect of Cylinder Shallow Shell
In this paper, the shape defect is studied by the experiment of drawing parts before and after trimming for the rectangle cylinder shallow shell. The mechanism of shape defect and the effect of forming condition and trimming on shape defect are discussed. And the influence laws of forming conditions on shape defect are achieved. Such as binder force, curvature radius, sheet thickness, yield strength and residual stress after trimming.
