• Grain boundaries and interfaces in slip transfer (2014, unknown): “Also, understanding the origins of cracks is critically important in many applications [52–54].”
• Slip transfer and deformation structures resulting from the low cycle fatigue of near-alpha titanium alloy Ti-6242Si (2018, background): “Furthermore, it is believed that hard/soft grain pairs act as fatigue initiation sites (Dunne et al., 2007a, 2007b; Dunne and Rugg, 2008) and this occurs by the formation of near-{0002} facets near-perpendicular to the loading direction on grains poorly oriented for <a> slip (‘hard grains’), due to…”

• Is stored energy density the primary meso-scale mechanistic driver for fatigue crack nucleation? (2018, background): “The frequency of successful attempts to jump the obstacles is given by the term − −( )( ) ( )ν exp sinh τ τΔFkT ΔVkT α cα , considering both forward and backward activation events (Dunne et al., 2007b).”
• Slip transfer across phase boundaries in dual phase titanium alloys and the effect on strain rate sensitivity (2018, methodology): “The detailed formulations of these CP and DDP models respectively have been described in earlier papers (CP: (Dunne et al., 2007; Zhang et al., 2016; Zheng et al., 2016b), DDP: (O'Day and Curtin, 2005; Zheng et al., 2016c, 2017b)), hence are only concisely covered here.”
• Crystal plasticity analysis of micro-deformation, lattice rotation and geometrically necessary dislocation density (2012, methodology): “…of GND density, and their inclusion in modelling studies related to indentation size effects (Britton et al. 2010a; Wilkinson & Randman 2010), facet fatigue (Dunne et al. 2007a; Dunne & Rugg 2008) and micro-deformation (Cheong et al. 2005; Cheong & Busso 2006), for example, is widespread.”

• The role of heterogeneous deformation on damage nucleation at grain boundaries in single phase metals (2009, background): “Such predictions require multiscale modeling approaches that are under development in a number of groups and laboratories (Hao et al., 2003, 2004; Clayton and McDowell, 2004; Voyiadjis et al., 2004; Buchheit et al., 2005; Dunne et al., 2007; Cheong et al., 2007).”
