Memory of rotation in residual stress of paste
Hiroki Matsuda, Michio Otsuki
We numerically investigate the stress distribution in pastes after horizontal rotation by using an elasto-plastic model. Residual stress remains as a memory of rotation. The stress…
Displacement correlations in a two-dimensional colloidal liquid and their relationship with shear strain correlations
Takeshi Ooshida, Takeshi Matsumoto, Michio Otsuki
Correlations of the displacement field in a two-dimensional model colloidal liquid is studied numerically and analytically. By calculating the displacement correlations and the she…
Scaling laws for velocity profile of granular flow in rotating drums
Hiroki Oba, Michio Otsuki
We theoretically and numerically investigate the steady flow of two-dimensional granular materials in a rotating drum using the discrete element method and a continuum model with t…
Critical scaling for dense granular flow between parallel plates near jamming
Michio Otsuki, Kenta Hayashi, Kiwamu Yoshii
We numerically study the flow of dense granular materials between parallel plates driven by an external force. The granular materials form a jammed solid-like state when the extern…
Control of Static Friction by Designing Grooves on Friction Surface
Wataru Iwashita, Hiroshi Matsukawa, Michio Otsuki
This study numerically investigated the friction of viscoelastic objects with grooves. A 3D viscoelastic block with grooves on a rigid substrate is slowly pushed from the lateral s…
