Abstract:

Constitutive equations for finite deformations of rate-independent materials with memory are discussed. The Piola stress is taken to be a functional of the path of deformation in strain space, independent of the rate of traversal of this path. The restrictions on the form of this functional arising from initial isotropy are exhibited. Differential and integral approximations to the functional are considered. A general theory of elastic-plastic materials, i. e. rate-independent materials with an elastic range, is formulated. Author
