Granular packing stress changes significantly after side walls move. Wall movement alters the stress state, creating a new equilibrium distinct from the initial settled state.

Area of Science:

  • Physics
  • Engineering
  • Materials Science

Background:

  • Granular materials exhibit complex behaviors under stress.
  • Understanding stress distribution in confined granular packings is crucial for various applications.

Purpose of the Study:

  • To investigate the impact of side wall movement on stress evolution in confined granular packings.
  • To compare the final stress state with the initial hydrostatic-like state.

Main Methods:

  • Discrete element method (DEM) simulations.
  • Molecular dynamics (MD) simulations.
  • Analysis of stress as a function of wall movement direction and velocity.

Main Results:

  • Wall movement fundamentally alters the stress state compared to the initial settled state.

  • Stress profiles evolve with wall velocity, showing initial minima and velocity-dependent steady states.
  • Janssen's model describes stress profiles at high wall velocities, with deviations at low velocities.
  • Increased particle-wall and particle-particle forces at the Coulomb criterion observed.

    • Conclusions:

    • Side wall movement significantly reconfigures stress in granular packings.
    • The final stress state is dependent on wall movement history and velocity.
    • Wall movement enhances force interactions within the packing.
