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…
Counter-flow induced clustering: Exact results
Amit Kumar Chatterjee, Hisao Hayakawa
We analyze the cluster formation in a non-ergodic stochastic system as a result of counter-flow, with the aid of an exactly solvable model. To illustrate the clustering, a two spec…
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…
Kinetic theory of discontinuous shear thickening of a moderately dense inertial suspension of frictionless soft particles
Satoshi Takada, Kazuhiro Hara, Hisao Hayakawa
We demonstrate that a discontinuous shear thickening (DST) can take place even in a moderately dense inertial suspension consisting of frictionless soft particles. This DST can be…
Discontinuous shear thickening of a moderately dense inertial suspension of hydrodynamically interacting frictionless soft particles
Satoshi Takada, Kazuhiro Hara, Hisao Hayakawa
We demonstrate that discontinuous shear thickening (DST) can occur even in moderately dense, inertial suspensions of hydrodynamically interacting, frictionless soft particles. Usin…
