Numerical failure analysis of a stretch-bending test on dual-phase steel sheets using a phenomenological fracture model (2010, methodology): “…have been employed to model AHSS: von Mises isotropic yield surface (Yoshida et al., 2000; Durrenberger et al., 2008); Hill’s (1948) quadratic orthotropic yield function (Banu et al., 2006; Chen and Koc, 2007); non-quadratic anisotropic Barlat et al. (2003) yield surface (Lee et al., 2005).”
On the determination of material parameters for internal variable thermoelastic-viscoplastic constitutive models (2007, background): “Estimating material parameters for constitutive models in such a way as to describe with precision the behaviour of the material is often a common need for the engineering community (see e.g. Mahnken, 2002; Li et al., 2002; Morbiducci, 2003; Love and Batra, 2005; Lee et al., 2005; Bocciareli et al.,”
A practical two-surface plasticity model and its application to spring-back prediction (2007, methodology): “The formulation and material characterization procedure for the modified Chaboche model is documented elsewhere (Lee et al., 2005b).”
