A Case of Torsion–tension in Plasticity – Analytical Treatment and Indirect Approaches

The plastic deformation of a thin-walled circular cylinder is considered for a specified sequence of torsion and tension. The case was originally intended for contrasting in general terms kinematic hardening with the isotropic hardening model. With the present account the analysis is accomplished presenting the closed-form solution for a linear yield stress and exploring approximations. In addition to the direct analytic treatment iterative procedures, numerical and successive functional update are investigated.
