Crystal Plasticity Finite Element Methods: in Materials Science and Engineering (2010, background): “Materials with large numbers of low-Σ boundaries (Kim and Oh, 2003; Palumbo, Lehockey, and Lin, 1998; Randle, 2004; Watanabe and Tsurekawa, 2004) that are well connected as networks (Schuh, Kumar, and King, 2003) exhibit higher flow stress and ductility than materials with few low-Σ boundaries (a we”
Overview of constitutive laws, kinematics, homogenization and multiscale methods in crystal plasticity finite-element modeling: Theory, experiments, applications (2010, background): “Materials with large numbers of low R boundaries [352–354] that are well connected as networks [355] exhibit higher flow stress and ductility than materials with few low R boundaries (a weak boundary percolation can occur if there are less than 78% low R boundaries [356]).”
The role of heterogeneous deformation on damage nucleation at grain boundaries in single phase metals (2009, background): “Materials with large numbers of low R boundaries (Palumbo et al., 1998, Kim et al., 2003, Watanabe and Tsurekawa, 2004; Randle, 2004) that are well connected in networks (Schuh, 2003, McGarrity et al., 2005) exhibit higher flow stress and ductility than materials with few low R boundaries.”
