The study reveals the stress and kinematic states in the extrusion of square sections from cylindrical billets, indicating key parameters for manufacturing.
With the help of the theory of plastic flow by the method of A. L. Vorontsov, all the formulas necessary for calculating the stresses and the force parameters of the process of extrusion or pressing of a section of square cross-section from a cylindrical billet have been obtained.
