The study of finite element method approach to backward extrusion of diving container

In the presented work, investigation of the axysymmetric backward extrusion process of the first stage of diving container is analysed and the general principles in the development of metal forming processes and process for semifinished product in particular are briefly discussed. Axisymmetric extrusion is chosen as an example for finite element modelling. This is carried out after making simplifying assumption of the deformation geometry. The prelimenary investigation on the simple backward extrusion model of lead billet using various finite elements are presented.
