An oscillatory simple shear flow of granular materials with different shear amplitudes is simulated...

...Dong Liao; Chao Zhou; Zhongxuan Yang In practical geotechnical engineering, soil elements in the ground often experience varying stress paths involving loading reversals. To better understand the incremental behaviour of granular material under these conditions and enhance associated constitutive...

...Yadong Wang; Xiaogang Guo; Wei Wu; Hongwei Zhou; Zhi Li Granular materials exhibit solid-like and fluid-like behaviour in different flow regimes, governed by intergranular frictions, collisions and viscous force from the interstitial fluid. In this paper, a state- and rate-dependent constitutive...

The model is extended from the existing cyclic densification model within the framework termed ‘shakedown surface model’, integrating breakage effects. In this model, shakedown thresholds, associated with material densification...
