Finite Element Results of Pressurized Thick Tubes Based on Two Elastic- Plastic Material Models

Abstract

The loading and unloading problems in thick tubes subjected to uniform internal pressure have been analyzed with the ADINA finite element code. The elastic-plastic materials are modeled by two strain-hardening rules- isotropic and kinematic. The von Mises yield condition, the associated flow theory, and a numerical results of the stresses and displacements for thick tubes with different wall ratios are obtained as functions of loading history. A comparison of numerical results based on two material models is made.
