DEFORMATION OF METALS UNDER COMPLEX LOADING WITH ABRUPT ROTATION OF THE AXES OF THE STRESS TENSOR

The influence of the complex loading history of a material on the change in its elastic moduli and the so-called additional loading moduli (slopes of initial linear portions of the curves of additional loading after preliminary simple loading) is analyzed. Information about programs and methods of processing the primary data of experiments with thin-walled tubular steel specimens loaded by an axial tensile force and torsion moment is presented.
