Analysis of stress-strain state during asymmetrical extension
The paper presents a new formulation of the problem in which the center of deformation is to consist of three, and not two, zones. We have examined the stressed state in the contact section, we have evaluated the relative magnitude of contact between the outside slider and the billet. We have obtained the borderline conditions to analyze the stressed state in the second section of the flange, the former being free from the outside slider.
