Diffuse failure in geomaterials: Experiments, theory and modelling (2011, unknown): “The CH model proposed by Chang and Hicher [55] uses the reverse order starting from the stress tensor to arrive at the strain tensor using the same techniques as in the above.”
Failure in rate-independent granular materials as a bifurcation toward a dynamic regime (2012, unknown): “For this purpose, using micromechanically-based models (see for example Chang and Hicher, 2005; La Ragione et al., 2008; Zhu et al., 2010) could be a powerful approach to penetrate down into the microstructural scale.”
Granular micromechanics based micromorphic model predicts frequency band gaps (2015, methodology): “The twelve separated equations of motion include two uncoupled equations for two transverse shear waves and one for a transverse rotational wave (a10 + a13) ψ(23),11 − (b2 + b3) ψ(23) = 1 3 ′d2ψ̈(23) (48a) (a10 + a13) ( ψ22,11 − ψ33,11 − (b2 + b3) (ψ22 − ψ33) = 1 3 ρ′d2 ( ψ̈22 − ψ̈33 ) (48b) (a10 − ”
A micromechanics-based model for sand-silt mixtures (2014, methodology): “The model to be proposed in this paper is based on the micromechanics model of sand first proposed by Chang and Hicher (2005) and further developed by Chang and Yin (2010a), Chang and Yin (2010b, Chang and Yin (2011), Chang, Yin, and Hicher (2011), Yin, Chang, and Hicher (2010) and Yin and Chang…”
Buckling force chains in dense granular assemblies: physical and numerical experiments (2009, background): “Not surprisingly, constitutive models which are based on the assumption of an affine deformation overpredict material stability, to the extent that shear banding and strain softening cannot be reproduced without need for supplementary and often ad hoc relations (Tordesillas and Walsh 2005 , Chang a”
