查询词典 large-diameter

The plastic deformation mechanism of the process is explained. The vector equations of the curved conical surface and the figure of the particle motion for the forming process of the bending tube are presented. The theoretical model of stress and strain fields of the forming process is deduced. The practical forming process of tubes of large diameter demonstrates the validity of the new type of design method of the ox-horned core bar and the computation formula of the length of the raw tube.
