A crystal symmetry-invariant Kobayashi--Warren--Carter grain boundary model and its implementation using a thresholding algorithm
Jaekwang Kim, Matt Jacobs, Stanley Osher +1
One of the most important aims of grain boundary modeling is to predict the evolution of a large collection of grains in phenomena such as abnormal grain growth, coupled grain boun…
Polycrystal plasticity with grain boundary evolution: A numerically efficient dislocation-based diffuse-interface model
Junyan He, Nikhil Chandra Admal
Grain structure plays a key role in the mechanical properties of alloy materials. Engineering the grain structure requires a comprehensive understanding of the evolution of grain b…
The Green tensor of Mindlin's anisotropic first strain gradient elasticity
Giacomo Po, Nikhil Chandra Admal, Markus Lazar
We derive the Green tensor of Mindlin's anisotropic first strain gradient elasticity. The Green tensor is valid for arbitrary anisotropic materials, with up to 21 elastic constants…
A unified framework for polycrystal plasticity with grain boundary evolution
Nikhil Chandra Admal, Giacomo Po, Jaime Marian
Plastic deformation in polycrystals is governed by the interplay between intra-granular slip and grain boundary-mediated plasticity. However, while the role played by bulk dislocat…
A non-singular theory of dislocations in anisotropic crystals
Giacomo Po, Markus Lazar, Nikhil Chandra Admal +1
We develop a non-singular theory of three-dimensional dislocation loops in a particular version of Mindlin's anisotropic gradient elasticity with up to six length scale parameters.…
