Rheology of two-dimensional crushable granular materials [PDF]
EPJ Web of Conferences, 2021 The rheology of two-dimensional crushable granular materials under shear is numerically studied using the discrete element method. We find that the mean fragment size changes as the shear strain increases while the shear stress is almost independent of ...

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.

Rheology of soft granular materials: uniaxial compression [PDF]
EPJ Web of Conferences, 2021 Soft granular materials are assemblies of highly deformable grains interacting via surface forces. The large grain deformations of these materials differ them from hard granular systems, in which, their behaviors are essentially governed by grain ...

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,
