Spring-back evaluation of automotive sheets based on isotropic-kinematic hardening laws and non-quadratic anisotropic yield functions: Part I: theory and formulation (2005, background): “While most kinematic hardening parameters were assumed constant, some kinematic hardening parameters were material functions varying with the plastic deformation (Geng et al., 2002; Geng and Wagoner, 2002; Khan and Huang, 1995).”
Simulation of springback variation in forming of advanced high strength steels (2007, background): “Geng and Wagoner [ 4 ] studied the effects of plastic anisotropy and its evolution in springback.”
Deep learning predicts path-dependent plasticity (2019, unknown): “However, complexity of computational plasticity models tends to substantially grow as material behavior and plastic effects become more intricate when addressing phenomena such as the Bauschinger effect (3, 4), ratcheting (5, 6), anisotropy (7, 8), viscoplasticity (9), permanent softening (10, 11), ”

Continuous, large strain, tension/compression testing of sheet material (2005, methodology): “Because of the need for more refined constitutive relations, many new continuum and physical models have been developed to describe materials that undergo load reversals (Chaboche, 1989; Geng, 2000; Chun et al., 2002; Geng and Wagoner, 2002; Kang et al., 2003; Colak, 2004).”

Complex unloading behavior: Nature of the deformation and its consistent constitutive representation (2011, background): “However, while it mimics many practical operations, it is complex to analyze (Li and Wagoner, 1998; Geng and Wagoner, 2002; Li et al., 2002a; Wagoner and Li, 2007) because of reversing strain paths (need to account Key: t = sheet thickness; UTS = ultimate tensile strength; eu, et = uniform, total…”
Spring-back evaluation of automotive sheets based on isotropic-kinematic hardening laws and non-quadratic anisotropic yield functions: Part II: characterization of material properties (2005, methodology): “To describe the hardening behavior including the Bauschinger and transient behavior during unloading, the combined isotropic-kinematic constitutive laws have been commonly considered (Chaboche, 1986; Geng et al., 2002; Geng and Wagoner, 2002; Ohno and Wang, 1993a,b; Chun et al., 2002).”
