Finite element analysis of torsional deformation

A finite element analysis using a generalized axisymmetric element for the plastic deformation behaviour of cylindrical copper samples during torsion was performed. The calculated hardness with the distance from the torsional axis is compared with the experimental results in the reference [F. Szeleky et al. Mater. Sci. Eng. A277 (2000) 148]. It was found that the finite element method using axisymmetric elements with twist could simulate the torsional deformation well except for the near-axis region, where further investigation is necessary.
