The second report dealt with the stress for each of the elastic and plastic deformations. The stress which specifies the equilibrium equations is common to the both deformations, being a tensor representing the actual force field. But the stress which describes the stress-strain or strain increment relations, i.e the state equations, is not common ; the stress describing the plasticity law being equivalent to that for the equilibrium equations, the stress describing the elasticity law is a modified stress derived from the former. Based on these dual definitions of strain, strain increment and stress, the theories of elasticity and plasticity will be seen to be established, for the whole range of small and finite deformations, in harmony of a refined contrast.
