适用范围：This SAE Recommended Practice describes methods for determining plastic deformation encountered in the forming or drawing of sheet steel. the preferred method for determining plastic strain is the circle grid and the severity curve. The scribed square and change in thickness methods may also be used to evaluate deformation during the forming of a flat sheet into the desired shape.
