Elastic-Plastic Loading and Unloading in a Thick Tube with Kinematic Hardening Theory

摘要

Using Tresca's yield criterion, its associated flow rule, and the linear hardening law, analytical solutions have been obtained for elastic-plastic loading and unloading problems in a thick tube subjected to uniform internal pressure. Explicit expressions for the displacement, strains, and stresses are presented herein, along with numerical results for a closed-end tube.
