Zusammenfassung:The paper deals with the calculation of the extrusion force using the results of the torsion test of aluminium alloy EN AW-2014. The mathematical model for the calculation of the extrusion force requires the knowledge of the functional relationship between the yield stress and the temperature, the deformation and the deformation rate. Based on the proposed mathematical model for the calculation of the yield stress, the functional relationship was derived to determine the extrusion force in the hot extrusion of semi-products of aluminium alloy EN AW-2014.
