Mixed-Mode Stress Intensity Factors for Tubes under Pure Torsion Loading

“…Yang [5] published a numerical simulation results for rounded bars but the samples had a curvature perpendicular to the loading axis. Harter [6] published preliminary results for plates under biaxial loading, which is not the same case as here, but a tube can be approximated to a plate is the distances are sufficiently small and a biaxial loading case with equal stresses produces similar effects as torsion in an inclined crack. Hos [7] subjected slim tubes to remote pure torsion and Vormwald et.…”
