Some Aspects of a Discontinuous Galerkin Formulation for Gradient Plasticity at Finite Strains
Part of the
book series (IUTAMBOOK, volume 11)
This work considers the extension of a model of gradient plasticity, previously analysed subject to the assumption of infinitesimal deformations, to the finite strain regime. The discontinuous Galerkin finite element method is used to solve the non-local expression of the plastic flow rule, thereby allowing the higher order terms that arise in the gradient formulation to be accommodated in an elegant manner.
