Consistent determination of geometrically necessary dislocation density from simulations and experiments (2018, background): “(40) involve minimising the total dislocation density (Demir et al., 2009; El-Dasher et al., 2003; Sun et al., 2000), or minimisation the equivalent line length (Wilkinson and Randman, 2010).”
Mapping and Assessing Plastic Deformation Using EBSD (2009, methodology): “The work of El-Dasher et al. (2003) used directionally solidified, columnar-grained Al in order to neglect the orientation gradient in the Z-direction.”
Simulation of polycrystal deformation with grain and grain boundary effects (2011, background): “…the assumption that the mean curvature j can be expressed as an averaged value of six in-plane components (Adams and Field, 1992; Sun et al., 2000; El-Dasher et al., 2003), j ffi 1 6 X3 i¼1 X2 j¼1 jjijj ¼ 1 6 X3 i¼1 X2 j¼1 d/i dxj : ð25Þ In order to obtain mean curvature, j, from the two-scale…”
A Review of Strain Analysis Using Electron Backscatter Diffraction (2011, methodology): “…OIM data can be performed to extract the GND tensor providing a more complete description of the strain state within the material ~Sun et al., 2000; El-Dasher et al., 2003; Field et al., 2005; Wilkinson et al., 2006b; Pantleon, 2008!. Figure 29 shows the w12 rotation component of the strain tensor…”
The effect of crystal orientation on the indentation response of commercially pure titanium: experiments and simulations (2010, background): “(4.4) Several authors (Adams 1997; Sun et al. 1998; El-Dasher et al. 2003; Field et al. 2005; Kysar et al. 2007; Larson et al. 2007; Demir et al. 2009; Pantleon et al. 2008; Zisman et al. 2008; Miyamoto et al. 2009) have used the lattice curvatures to calculate densities of GNDs within samples,…”
