Asymptotic behaviour of granular materials
Original language description
The concept of the asymptotic behaviour of particulate materials is described, including its enhancement by considering asymptotic states in extension. A 3D discrete element model with elastic spherical particles and the granulometry of a real sand is set up. The numerical sample is stretched from di?erent initial states, and the in?uence of the strain rate direction on the ?nal state is studied within the stress ratio, void ratio and mean stress space. Asymptotic behaviour is clearly observed, althoughthe grains remain intact (no grain crushing is considered). The extension asymptotic states are observed, and the notion of a normal extension line is introduced. The extension asymptotic states coincide with the peak states observed in the shear testswith constant stress path direction in dense samples.
