Plasticity size effects in free-standing submicron polycrystalline FCC films subjected to pure tension (2004, unknown): “This leaves an intermediate region where strain gradient plasticity theory has been proposed to describe material behavior (Aifantis, 1992; Fleck and Hutchinson, 1993, 1997; Fleck et al., 1994; Gao et al., 1999a, b; Huang et al., 2000; Hutchinson, 2000; Bazant and Guo, 2001).”
Plastic deformation of freestanding thin films: Experiments and modeling (2006, background): “Motivated by these experimental observations, a variety of theoretical frameworks have been developed to incorporate one or more material length scales into a theory of plastic flow, e.g. Gao et al. (1999), Acharya and Bassani (2000), Fleck and Hutchinson (2001), Gurtin (2002).”
Gradient plasticity theory with a variable length scale parameter (2005, methodology): “For instance, many authors tend to write sf ¼ sref þ abG ffiffiffiffiffi qT p , where qT is a linear sum of qS and qG, such that qT = qS + qG (e.g. Ashby, 1970; Stelmashenko et al., 1993; De Guzman et al., 1993; Fleck et al., 1994; Ma and Clarke, 1995; Nix and Gao, 1998; etc.).”
Extraordinary strain hardening by gradient structure (2014, background): “Consequently, the strain gradient is produced near the border between the unstable surface layers and the stable central core (11, 12), where strain continuity is required to keep material continuity.”
Simulation of polycrystal deformation with grain and grain boundary effects (2011, background): “…Li, 1963; Ashby, 1970) or via continuum constitutive equations coupled to an arbitrary length scale representing the microstructure size (Fleck et al., 1994; Fleck and Hutchinson, 1997; Nix and Gao, 1998; Gurtin, 2000, 2002; Gao et al., 1999; Huang et al., 2000; Abu Al-Rub and Voyiadijus, 2006).”
A physically based gradient plasticity theory (2006, background): “(22) is similar to that of the MSG and TNT plasticity theories (e.g., Nix and Gao, 1998; Gao et al., 1999a,b; Huang et al., 2000a; Gao and Huang, 2001).”
Thermodynamic framework for coupling of non-local viscoplasticity and non-local anisotropic viscodamage for dynamic localization problems using gradient theory (2004, methodology): “The viscoplasticity internal variables r2p and r2 are related to the total dislocation density and the microdamages (i.e. microcracks and microvoids) evolution, which introduces the viscoplasticity long-range microstructural interaction between SSD and GND, dislocations and microdamages, and disloca”
Combining Gradient Structure and TRIP Effect to Produce Austenite Stainless Steel with High Strength and Ductility (2016, background): “Strain partitioning causes strain gradient at phase boundaries, which is accommodated by geometrically necessary dislocations [25,26] and consequently enhances strain hardening [27].”
