Shear-cell -- MD simulation


Using soft sphere, time-driven molecular dynamics (MD) with 3386 particles, the effect of density on the collective shear behavior is examined.
The particle contacts are modelled as linear springs with linear damping. The tangential forces are linear springs which slip when the Coulomb force is exceeded.

Displacement: Shear localization

Medium density [2.8 MB]
High density [2.8 MB]
Low density [2.7 MB]
In order to visualize the displacement in the shear-cell, the particles are initially color-coded with respect to their vertial position and keep the color during the simulation.

Potential Energy: Force Chains

Medium density [3.0 MB]
High density [0.8 MB]
Low density [2.6 MB]
In order to visualize the potential energy (and thus the stress that the particles feel), the particles are color-coded red, green and blue for high, medium and low potential energy, respectively.

Kinetic Energy: Momentum Waves

Medium density [3.3 MB]
High density [2.7 MB]
Low density [3.2 MB]
In order to visualize the kinetic energy, the particles are color-coded red, green and blue for high, medium and low kinetic energy, respectively.
