Characterization of the post-necking strain hardening behavior using the virtual fields method (2013, methodology): “This approach has been applied to tensile specimens with a circular cross section (Bridgman, 1952; Mirone, 2004) and with a rectangular cross section (Ling, 1996; Zhang et al.”
Stress–strain curves of metallic materials and post‐necking strain hardening characterization: A review (2019, background): “It can be seen that when n=1, Equations (48) and (50) take the same form.”
A hybrid approach for modelling of plasticity and failure behaviour of advanced high-strength steel sheets (2013, background): “Mirone (2004) proposed a phenomenological formula for true stress and strain curve after necking for a round bar tensile test.”
A new method for acquiring true stress–strain curves over a large range of strains using a tensile test and finite element method (2008, methodology): “…researchers have tried to obtain true stress–strain curves using finite element methods, see e.g. (Cabezas and Celentano, 2004; Campitelli et al., 2004; Choi et al., 1997; Husain et al., 2004; Isselin et al., 2006; Lee et al., 2005; Mirone, 2004; Nayebi et al., 2002; Springmann and Kuna, 2005).”
