Modeling of deformation behavior and texture evolution in magnesium alloy using the intermediate ϕ-model

Mechanical behavior of Mg subjected to strain path changes: Experiments and modeling

“…Magnesium alloys have low density and high specific strength and have been applied in lightweight structural parts of fuel efficient vehicles during the last two decades (Li et al, 2014;Mayama et al, 2011;Paliwal and Jung, 2014;Sánchez-Martín et al, 2014). However, the highly directional plastic properties of HCP crystals, and the fact that slip and twinning modes exhibit large differences in their activation stresses, makes the plastic response of HCP metals complex and very anisotropic (Agnew et al, 2001Brown et al, 2005Brown et al, , 2012Chapuis et al, 2014;Ma et al, 2012;Piao et al, 2012;Schoenfeld et al, 1995;Zhang et al, 2011).…”

A microstructure based analytical model for tensile twinning in a rod textured Mg alloy

“…The effect of twinning has been incorporated into various crystal plasticity codes (Beyerlein et al, 2011;Beyerlein and Tome, 2010;Capolungo et al, 2009;Clausen et al, 2008;Fernández et al, 2013;Gu et al, 2013;Li et al, 2013;Liu and Wei, 2013;Niezgoda et al, 2013b;Oppedal et al, 2011;Oppedal et al, 2013;Proust et al, 2009;Wang et al, 2010a;Wang et al, 2013a;Wang et al, 2013b). These capture the strong asymmetric anisotropy but typically do so without explicitly considering twin nucleation and growth, which operate under different stresses (Christian and Mahajan, 1995).…”

Effect of realistic 3D microstructure in crystal plasticity finite element analysis of polycrystalline Ti-5Al-2.5Sn

“…Crystal plasticity theory based models on the other hand, spatially discretize (representative) volumes of microstructure and, thus, can directly apply realistic boundary conditions to realistic microstructures (Roters et al, 2010). Because of this more physically based stucture, models based on crystal plasticity generally provide a more accurate prediction of local deformation history, as demonstrated by many studies (e.g., Busso et al, 2000;Busso, 2004, 2006;Gao et al, 1999;Fleck et al, 1994;Kuhlmann-Wilsdorf, 1999;Rehrl et al, 2012;Li et al, 2014;Liu and Wei, 2014) . 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 Nevertheless, correct prediction of grain-scale deformation histories from crystal plasticity based models depends on validated constitutive models for crystal plasticity.…”
