Approximation model of the stress-strain curve for deformation of aluminium alloys

[摘要] 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 perdormed in a servohydraulic plastomer. Deformation curves have been described by means of...
