This analysis calculates stresses and force parameters in internal radial extrusion of pipe billets, highlighting implications for material processing.
Using the theory of plastic flow according to the method of A. L. Vorontsov, the formulas necessary for calculating the stresses and force parameters of the process of internal radial extrusion of a pipe billet have been obtained. The expansion force acting on the upper mandrel and the maximum pressure acting on the die wall were determined.
