A modified Nadai's method is proposed to determine the shear stress-strain curve by use of a solid circular cylinder subjected to torsional load. The modification is accomplished by taking into account the axial length change of the specimen. The method is extended to give the shear stresses in tubular specimens.A series of experiments on annealed isotropic high purity .
