The main purpose of this paper is to give a mathematical description of flow stress of examined aluminium alloys on the basis of upsetting tests performed in a servohydraulic plastometer. Deformation curves have been described by means of the Sellars-Tegart-Garofalo equation, with the aid of linear regression analysis and by the neural network method implemented in the NEUREX program.
