Analysis of Torsional Hysteresis Behavior of Shaft

In this paper, using the Abaqus finite element software, the torsional hysteresis of X۵۲, X۶۰, X۶۵ steels under loadings with different torsion values, has beennumerically investigated and they are compared to each other. The shear stress, effective stress, residual stress and elastic and plastic shear strain distribution are presented in the numerical results. In this analysis, the “chaboche” kinematic hardening theory has been used to predict the behavior of the material in the plastic region. By comparing the difference percentage graphs of the steels under the same load, it has been concluded that the hysteresis loops in X۶۵ steel will become stable sooner than X۶۰ and in X۶۰ steel they become stable sooner than X۵۲.
