In 1971, Lin showed a physical theory of plasticity which seems to represent the actual mechanism of plasticity better than other theories. Since then, much work has been done to improve this theory and to extend this theory to creep. This improved and extended theory is reviewed and given here. Some differences between the present theory and the self consistent theory are discussed. Present theory satisfies the conditions of equilibrium, continuity of displacement and the dependency of slip on the resolved shear stress throughout the polycrystal. The calculated results agree well with most experiments.
