An extended three-field principle to scale-bridge the granular micromechanics of polymer-bonded particulate materials

EC Bryant, NA Miller, KC Bennett - Computer Methods in Applied …, 2023‏ - Elsevier
Observed phenomena of damage, viscoelasticity, and viscoplasticity in polymer-bonded

Meso-scale size effects of material heterogeneities on crack propagation in brittle solids

L Li, J Rao, T Hufnagel, KT Ramesh - arxiv preprint arxiv:2309.12916, 2023‏ - arxiv.org
Brittle solids are often toughened by adding a second-phase material. This practice often
results in composites with material heterogeneities on the meso scale: large compared to …

Viscoelastic mechanics of two-dimensional granular lattices

S Selvaraju, SP Joshi, N Karanjgaokar - … of the Mechanics and Physics of …, 2024‏ - Elsevier
We study the rate-dependent mechanics of viscoelastic granular packings. Using a two-
dimensional, square lattice of particles as a motif mimicking nominally mono-disperse …

Shear behaviour of sand–rubber mixtures: interpretation from energy transformation and force chain evolution

N Guo, Y Shi, Z Hu, Z Yang - Géotechnique, 2023‏ - icevirtuallibrary.com
This study investigates the effect of rubber particles on biaxial shear responses of sand–
rubber mixtures (SRMs) using a multibody mesh-free method, which enables the flexible …
