Existence and Uniqueness for Rate-Independent Infinitesimal Gradient Plasticity with Isotropic Hardening and Plastic Spin (2010, background): “Another irrotational gradient plasticity model has been considered in [23, 24], where gradient effects appear only through a dependence of the yield limit on spatial gradients of the equivalent plastic strain , i.”
Mixed variational principles and robust finite element implementations of gradient plasticity at small strains (2013, methodology): “Numerical implementations of gradient plasticity at small strains in terms of discontinuous Galerkin methods are outlined in [31, 32].”
A unifying perspective: the relaxed linear micromorphic continuum (2013, unknown): “and leads to some difficulties when one implements nonlinear pde-systems due to couplings with plasticity theory [138, 139, 140, 45, 126, 43].”
