A controlled Poisson Voronoi tessellation for grain and cohesive boundary generation applied to crystal plasticity analysis

► A method for virtual grain structure representation with cohesive grain boundaries. ► An automatic method for partitioning multiple-junctions into quadrilaterals. ► Inter-granular crack initiation and propagation simulated using crystal plasticity. ► Fracture and deformation studied for uniaxial tension of a free cutting steel.
