Initiation of localized shear zones in viscoelastoplastic rocks (2006, methodology): “So far two main groups of models have been employed: (1) models in which a damagerheology results in localization [e.g. Bercovici , 1993, 1996; Tackley , 1998, 2000; Bercovici , 2003; Auth et al., 2003; Ogawa, 2003] and (2) models in which a localization is caused by shear-heating in combination…”
Mechanisms for the generation of plate tectonics by two-phase grain-damage and pinning (2012, background): “…during deformation, and that subsequent material damage survives for geologically extensive periods even after deformation ceases (Bercovici, 1998; Tackley, 2000c; Bercovici et al., 2001a,b; Auth et al., 2003; Bercovici and Ricard, 2003, 2005; Ricard and Bercovici, 2003, 2009; Landuyt et al.,…”
A free plate surface and weak oceanic crust produce single‐sided subduction on Earth (2012, methodology): “…(Figure 2) are an order of magnitude smaller than laboratory values [Kohlstedt et al., 1995], consistent with previous studies on yielding-induced plate tectonics [Foley and Becker, 2009;Moresi and Solomatov, 1998; Tackley, 2000a, 2000b; Trompert and Hansen, 1998; van Heck and Tackley, 2008].”
Plate tectonics on super-Earths: Equally or more likely than on Earth (2011, background): “Later some studies included more Earth-like features such as history dependent weakening (Tackley, 2000b, Ogawa, 2003) and a low viscosity asthenosphere (Tackley, 2000b, Richards et al., 2001).”
On the effect of temperature and strain-rate dependent viscosity on global mantle flow, net rotation, and plate-driving forces (2006, unknown): “Such conditions are given for the case of weak zones at plate boundaries (e.g. Zhong et al. 1998 ) or non-linear, strain-weakening rheologies (Bercovici 1995; Tackley 2001b).”
Mantle dynamics in super-Earths: Post-perovskite rheology and self-regulation of viscosity (2012, background): “If instead 399 the stagnant lid mode were present then downwellings would have a very small temperature 400 contrast of order the rheological temperature scale (Solomatov, 1995) and would therefore be 401 barely visible or invisible in these plots.”
A thermodynamically self-consistent damage equation for grain size evolution during dynamic recrystallization (2011, background): “This provides a memory to the mechanical behaviour of the lithosphere, an ingredient that is missing to the models of convection with selfconsistent plates (i.e. Tackley 2000; Stein et al. 2004).”
The effect of rheological parameters on plate behaviour in a self-consistent model of mantle convection (2004, methodology): “Especially convection with a pressure-dependent viscosity has been demonstrated to induce long wavelength flow patterns (e.g. Balachandar et al., 1992; Hansen et al., 1993; Bunge et al., 1997; Tackley, 2000c) which would be suppressed in small aspect ratio domains.”
Strong heterogeneity caused by deep mantle layering (2002, background): “Compositionally buoyant continents would add additonal heterogeneity at the top [Tackley, 2000c].”
