Abstract

One of the problems associated with the use of the Hencky equivalent strain in the analysis of experiments in large shear is that it cannot be paired with a work-conjugate equivalent stress. A further problem is associated with the observation that the textures developed in shear differ sharply from those formed during tension or compression, so that the rates of work hardening are also different. The effects of these differences on the von Mises equivalent stress/equivalent strain flow curves determined by testing are discussed.
