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…

Diffuse-interface polycrystal plasticity: Expressing grain boundaries as geometrically necessary dislocations
Nikhil Chandra Admal, Giacomo Po, Jaime Marian
The standard way of modeling plasticity in polycrystals is by using the crystal plasticity model for single crystals in each grain, and imposing suitable traction and slip boundary…
