Plastic deformation being essentially a hysteresis phenomenon, real metals usually exhibit anisotropy and the Bauschinger effect as well as work-hardening due to strain history. The existing theory of plasticity limited to the description of ideal plastic solid, is not capable of describing the plastic deformation of such real metals. In the present paper, a new theory "The Strain History Theory of Plasticity" proposed by one of the authors being applied to the general loading processes of combined stress of tensiontorsion after simple tension and torsion respectively, the yield condition, the rate of work-hardening and the stress-strain increment relation proper to a metal and their dependence on the strain history are deduced.
