Abstract

A new phenomenological model for strain hardening in f.c.c. metals is combined with the polycrystal approach of Budiansky and Wu (Proc. 4th U.S. Natn. Congress of Applied Mechanics, Vol. 2. pp. 1175–1185. Pergamon Press, Oxford, 1962). The strain hardening is assumed to be the result of increasing dislocation densities, where dislocations of opposite polarity can annihilate each other. Back stresses play only a minor role. The numerical results of this model, which contains only six adjustable parameters. are in good agreement with experimental Bauschinger and x-y-tests on commercial copper at room temperature
