| Abstract: | This paper sets up the calculation mathematic model of stress - strain and gives the analyses of bending moment in the round comer and of the pressure - pad - force in the flange which get calculation formulas for changeable forces, according to the change of every zone of sheets being drawn. Then, the author verifies these formulae and gives the conclusion about their effect. |
