The task is interesting and the deflection of nozzle withdrawal is a special process. It is a voluminous tensile state in the area of deformation with applied force pulling through a certain contact area of the initial deformation and the calibration part. An important step is to know the degree of reduction (the degree of deformation) and to introduce it correctly in the simulation model. In addition, the profile of the drawing tool, as well as the lubricant, is essential. The chemical composition and the pre-supply (supply) of material from a previous technological process should not be omitted. Last but not least, the bulkiness of the tool and the deformation material.
For more information, I can be more useful.
With a wish for success in solving an interesting task.
