Bulk Modulus along Jamming Transition Lines of Bidisperse Granular Packings
Juan C. Petit, Nishant Kumar, Stefan Luding +1
We present 3D DEM simulations of bidisperse granular packings to investigate their jamming densities, , and dimensionless bulk moduli, , as a function of the size ratio, $δ…
Additional transition line in jammed asymmetric bidisperse granular packings
Juan C. Petit, Nishant Kumar, Stefan Luding +1
We present numerical evidence for an additional discontinuous transition inside the jammed regime for an asymmetric bidisperse granular packing upon compression. This additional tr…
Macroscopic model with anisotropy based on micro-macro informations
Nishant Kumar, Stefan Luding, Vanessa Magnanimo
Physical experiments can characterize the elastic response of granular materials in terms of macroscopic state-variables, namely volume (packing) fraction and stress, while the mic…
Tuning the bulk properties of bidisperse granular mixtures by small amount of fines
Nishant Kumar, Vanessa Magnanimo, Marco Ramaioli +1
We study the bulk properties of isotropic bidisperse granular mixtures using discrete element simulations. The focus is on the influence of the size (radius) ratio of the two const…
Memory of jamming - multiscale models for soft and granular matter
Nishant Kumar, Stefan Luding
Soft, disordered, micro-structured materials are ubiquitous in nature and industry, and are different from ordinary fluids or solids, with unusual, interesting static and flow prop…
Rheological Behavior of Aqueous Suspensions of Laponite: New Insights into the Ageing Phenomena
Yogesh M Joshi, G. Ranjith K. Reddy, Ajit L. Kulkarni +2
In this paper, ageing behavior of suspensions of laponite with varying salt concentration is investigated using rheological tools. It is observed that the ageing is accompanied by…
