A method is derived whereby warping shear stresses due to restraints or the variation of torque along a bar can be computed using finite elements. For completeness, it is also indicated how the restrained warping longitudinal stresses are calculated. In this paper, the effects of nonuniform torsion are incorporated into Herrmann.s solution for the case of thin-walled open sections.
