On the evolution of crystallographic dislocation density in non-homogeneously deforming crystals (2004, background): “A general form of these con7gurational stresses with the dipolar dislocation density in the denominator has not been proposed, but rather additional material constants with units of length have been considered (Bittencourt et al., 2003).”
Size effects and idealized dislocation microstructure at small scales: Predictions of a Phenomenological model of Mesoscopic Field Dislocation Mechanics: Part I (2005, background): “Gurtin, 2000; Bittencourt et al., 2003; Arsenlis et al., 2002; Evers et al., 2004; Ortiz and Repetto,”
The role of interfaces in enhancing the yield strength of composites and polycrystals (2005, background): “Examples of work of this type include Cleveringa et al. (1997), Shu et al. (2001), Bittencourt et al. (2003).”
A comparison of dislocation induced back stress formulations in strain gradient crystal plasticity (2006, background): “Simple shearing of a constrained strip has been examined by Shu et al. (2001), Evers et al. (2004a), Bittencourt et al. (2003) and Fredriksson and Gudmundson (2005) and leads to the development of deformation gradients resulting in boundary layers with vanishing plastic deformation.”
