Torsion of a Two-part Cylindrical Rod

Abstract

This paper concerns an analysis of torsional stresses in a two-part cylindrical rod. At the corner of the rod, the stresses have singularities with unknown order. Then, a stress analysis is carried out by the classical method without consideration of the stress singularity. The stress states of the rod are given numerically for some cases. The results show that the order of the stress singularity depends on the shear modulus of the rod only.
