The paper is concerned with a numerical procedure to solve the elastic-plastic torsion of a bar using the variational inequality concept. The finite element method with SOR (successive over relaxation) technique is employed to solve the variational inequality as a constrained minimuzation problem. Circular, square, L-shaped cross sections, and square cross section with a slit are considered as numerical examples. Von Mises yield criteria is employed. © 1980.
