A crystal plasticity FE model for deformation with twin nucleation in magnesium alloys (2015, methodology): “The crystal plasticity constitutive model is adapted from the size and time dependent, finite strain models that have been developed for Ti alloys in (Hasija et al., 2003; Deka et al., 2006; Venkataramani et al., 2007, 2008; Anahid et al., 2011; Ghosh and Chakraborty, 2013).”
Slip transfer across phase boundaries in dual phase titanium alloys and the effect on strain rate sensitivity (2018, background): “They have been reported to show strong positive strain rate sensitivity (SRS) at ambient temperature (e.g. 20 °C) (Hasija et al., 2003) resulting in the observed creep and stress relaxation.”
Slip transfer and deformation structures resulting from the low cycle fatigue of near-alpha titanium alloy Ti-6242Si (2018, background): “…the micromechanical loading state e the compatibility of the elastic moduli and plasticity between the grains, and therefore the stress perturbations associated with discontinuities such as grain boundaries (Hasija et al., 2003; Dunne et al., 2007a; Venkatramani et al., 2007; Dunne and Rugg, 2008).”
On the mechanistic basis of deformation at the microscale in hexagonal close-packed metals (2015, background): “The first rigorous analysis and explanation of the effect of dwell was presented by Hasija et al [122] who explained the phenomenon of load shedding (see section 6.”
Dwell fatigue crack nucleation model based on crystal plasticity finite element simulations of polycrystalline titanium alloys (2011, methodology): “Ghosh et al. have developed experimentally validated, size-dependent crystal plasticity FE models for titanium alloys in Hasija et al. (2003), Deka et al. (2006), Venkatramani et al. (2006), and Venkataramani et al. (2007), especially for modeling the load shedding phenomenon.”
A systematic study of hcp crystal orientation and morphology effects in polycrystal deformation and fatigue (2007, methodology): “It is comparatively well characterized in terms of its hcp anisotropic elasticity properties (Hasija et al. 2003), and owing to its aluminium content (greater than 5%), does not show significant deformation by twinning (Williams et al. 2002; Xiao 2005).”
