Method of Predicting Necking True Stress in a Thin-Walled Tube Under a Complex Stress State

Method of Predicting Necking True Stress in a Thin-Walled Tube Under a Complex Stress State

Method of predicting the strength of thin-walled tubes under a complex stress state, taking into account changes in the initial dimensions, is proposed. Uniform plastic deformation of a thin-walled tube under short-term static load by internal pressure and axial tension is considered. The tube mater...
