Abstract The stress—strain relation of polycrystalline Cu-1 at% Co wire samples were investigated by simultaneous torsion and extension. For this stress state a single valued stress—strain relation, valid at the outer radius of the sample, can be derived, which gives results equivalent to a pure tensile test. With the analysis of the plastic work the generalized flow law is proved. It is shown that the tensile stress is not homogeneously distributed along the cross-section of the wire during simultaneous torsion and extension. Its value, valid at the outer radius, can be separated into two parts, one originating from the tensile force and another one which is proportional to the torsional shear stress. An extrapolation to the case of pure torsion is given.
