In this study, we reconsider the problem of an elastic-plastic torsion of a bar made of work hardening material. Nonlinear partial differential equation derived is reduced to a well known Laplace equation by means of transformation functions and stresses ? xz, ? yz and the torque T are analytically found for elliptical and circular cross sections. It is further shown that the stresses and the twisting moment do not depend on the value of n in the stress-strain law.
