A finite element method to calculate geometrically necessary dislocation density: accounting for orientation discontinuities in polycrystals
Strain gradients have been used to link various microscale deformation phenomena to the mechanical response of a polycrystalline material, revealing sub-crystal deformation structures. The strain gradients are computed in terms of the orientation gradients and then converted to geometrically necessa...
