Detecting vorticity in cohesive deformable granular material [PDF]
EPJ Web of Conferences, 2021 Numerical models of granular materials are useful in tribology, and can be used to predict wear and friction in contacts. DEM-like simulations are used to model particles of third-body, which are partly wear debris from rubbing bodies.

Memory Effects in Granular Materials [PDF]
Physical Review Letters, 2000 We present a combined experimental and theoretical study of memory effects in vibration-induced compaction of granular materials. In particular, the response of the system to an abrupt change in shaking intensity is measured. At short times after the perturbation a granular analog of aging in glasses is observed.

Exploring chemo-mechanics of granular material using DEM [PDF]
EPJ Web of Conferences, 2021 Particle Size Distribution (PSD) is one of the prime guiding factors of granular media response. Degradation via weathering is a process, which brings about a gradual shift in the PSD. In nature, chemically sensitive material like calcite undergoes chemo-

Chemosensors, 2022 Grain size is one of the most important physical parameters for randomly packed granular (RPG) materials. Its estimation, especially in situ, plays a key role in many natural and industrial processes.

Nihon Kikai Gakkai ronbunshu, 2019 We investigated the damping mechanism of a granular-material damper for a structure with a high natural frequency. We focused on the flow of the granular-material vibration energy and considered its relationship with the damping characteristics.

On the Failure of the Granular Material
Soils and Foundations, 1967 SYNOPSIS Notwithstanding the statistical theory of mechanics of granular material proposed by the senior author, was established basing on experimental evidences, still it contained several uncertain assumptions. By the bi-axial compression tests on assemblage of equal balls, almost all of assumptions were ascertained. Observing the failure phenomena,

Viscoelasticity of granular materials
Mechanics of Materials, 1995 Abstract In a former work (V.T. Granik and M. Ferrari (1993), Microstructural mechanics of granular media, Mech. Mater. 15, 301–322) a micromechanical theory for elastic granular media was deduced on the basis of the identification of the constituent grains with the nodes of a Bravais lattice.

Scaling properties of granular materials [PDF]
Physical Review E, 2001 Given an assembly of viscoelastic spheres with certain material properties, we raise the question how the macroscopic properties of the assembly will change if all lengths of the system, i.e. radii, container size etc., are scaled by a constant. The result leads to a method to scale down experiments to lab-size.

Nihon Kikai Gakkai ronbunshu, 2017 We investigated the damping mechanism of a granular material damping system applied to reducing vibration in structures that have a high natural frequency and small vibration displacement. Experiments were conducted under several conditions of total mass
