| Abstract: | The paper presents the plastic deformation of the steel helmet with cold extrusion moulding. The plastic streamline of the plastic mould-making process for ellipse thin plate are described. The distribution of the slip -line is established by plastic streamline. Using slip-line method the extrusion force of plastic moulding of the steel helmet is calculated. Applied examples is given. |
