Eigenvalue analysis of stress-strain curve of two-dimensional amorphous solids of dispersed frictional grains with finite shear strain
Daisuke Ishima, Kuniyasu Saitoh, Michio Otsuki +1
The stress-strain curve of two-dimensional frictional dispersed grains interacting with a harmonic potential without considering the dynamical slip under a finite strain is determi…
An exact expression of three-body system for the complex shear modulus of frictional granular materials
Michio Otsuki, Hisao Hayakawa
We propose a simple model comprising three particles to study the nonlinear mechanical response of jammed frictional granular materials under oscillatory shear. Owing to the introd…
Static Friction Coefficient Depends on the External Pressure and Block Shape due to Precursor Slip
Wataru Iwashita, Hiroshi Matsukawa, Michio Otsuki
Amontons' law states that the maximum static friction force on a solid object is proportional to the loading force and is independent of the apparent contact area. This law indicat…
Mechanical and geometrical properties of jammed wet granular materials
Kiwamu Yoshii, Michio Otsuki
We numerically investigate the mechanical and geometrical properties of dense wet granular particles with irreversible attractive interaction. The shear modulus exhibits two inflec…
Theory of rigidity and numerical analysis of density of states of two-dimensional amorphous solids with dispersed frictional grains in the linear response regime
Daisuke Ishima, Kuniyasu Saitoh, Michio Otsuki +1
Using the Jacobian matrix, we obtain theoretical expression of rigidity and the density of states of two-dimensional amorphous solids consisting of frictional grains in the linear…
Correlation function and linear response function of homogeneous isotropic turbulence in the Eulerian and Lagrangian coordinates
Takeshi Matsumoto, Michio Otsuki, Takeshi Ooshida +1
We study the correlation function and mean linear response function of the velocity Fourier mode of statistically steady-state, homogeneous and isotropic turbulence in the Eulerian…
