Abstract
G-structures are the geometric backbone of the theory of material unif ormity in continuum mechanics. Within this geometrical framework, plas ticity is seen as a result of evolving distributions of inhomogeneity with driving force provided by the material Eshelby stress tenser. Con stitutive principles governing the time evolution of the G-structure u nderlying the finite-strain theory of elastoplasticity are proposed to gether with a thermodynamically admissible formulation.
