Study of the interplay between lower-order and higher-order energetic strain-gradient effects in polycrystal plasticity

Strain-gradient (SG) plasticity refers to a class of non-local theories in which gradients of plastic slip determine the storage of geometrically necessary dislocations, introducing a length-scale dependence in the mechanical behavior of crystalline materials, which is otherwise lacking in local the...
