Using Wallace's analysis for steady weak shocks, this paper establishes for Cu, Ur, and 6061T6Al an approximate relations between the shock strength and the maximum deviatoric stress, tau/sub m/, and plastic strain at tau/sub m/. In addition it is shown that the plastic strain rate is very nearly proportional to the total normal strain rate at tau/sub m/. These results and the universal shock strength/strain rate relation of Swegle and Grady are used to draw conclusions about the general plasticity constitutive relation.
