Study on the Principle of Thin-Wall Tube Necking Deformation

Yu Yanqin et al(36)  
According to plastic forming theory, the characteristics of thin_wall tube necking deformation while axially loaded were stated. The expression of necking force was derived, and the best half taper angle of the matrix for necking deformation was extracted. The main factors affecting the best half taper_angle value of the matrix were analyzed, and verified by tests.
