Abstract
A new hardening law is introduced into the classical incremental theor y of plasticity for initially isotropic solids allowing us not only to rigidly translate, transversely isotropically deform and rotate, but also to distort the yield surface. The law, on the whole, can satisfac torily describe modifications of the surface experimentally obtained b y other authors in complex biaxial tension-torsion Loading of thin-wal led tubular specimens of pure aluminum.
