Complex unloading behavior: Nature of the deformation and its consistent constitutive representation (2011, methodology): “…model consistent with the characteristics discussed above, tensor geometric concepts from two-yield-surface (TYS) plasticity theories (Krieg, 1975; Dafalias and Popov, 1976; Tseng and Lee, 1983; Ohno and Kachi, 1986; Ohno and Satra, 1987; Geng and Wagoner, 2000, 2002; Yoshida and Uemori, 2002,…”
Study on the influence of work-hardening modeling in springback prediction (2007, background): “In brief, springback is influenced by material properties such as elastic behavior (Morestin and Boivin, 1996; Cleveland and Ghosh, 2002; Yang et al., 2004; Alves et al., 2006), the initial anisotropy resulting from sheet rolling conditions (Leu, 1997; Geng and Wagoner, 2002; Papeleux and Ponthot,…”
Spatio-temporal characteristics of the Portevin-Le Châtelier effect in austenitic steel with twinning induced plasticity (2009, background): “Microplastic strains during unloading result from the ‘‘backwards” movement of dislocations from regions of dislocation ‘‘pile-ups” (Cleveland and Ghosh, 2002).”
