Force distributions in granular materials are similar in 2D and 3D, and for soft particles. Forces below the mean do not contribute to shear stress, acting like a fluid.

Area of Science:

  • Physics
  • Materials Science
  • Mechanical Engineering

Background:

  • Understanding force transmission in granular materials is crucial for predicting their mechanical behavior.
  • Previous studies focused mainly on 2D systems of hard particles.

Purpose of the Study:

  • To systematically investigate force distributions in 3D granular packings, including soft particles.
  • To validate and extend findings from 2D systems to 3D.
  • To analyze the role of forces below the mean in shear stress and static equilibrium.

Main Methods:

  • Systematic numerical investigation of force distributions.
  • Simulation of granular packings with varying particle properties (hard/soft) and dimensions (2D/3D).
  • Development of a model for exact computation of contact forces at static equilibrium.

Main Results:

  • Force transmission features observed in 2D systems are also present in 3D and for soft particles.
  • Normal force distribution exhibits exponential decay above the mean and power-law or uniform distribution below the mean, depending on static equilibrium.
  • Forces below the mean do not contribute to shear stress, forming a fluid-like subnetwork.

Conclusions:

  • The principles of force transmission in granular materials are general across dimensions and particle types.
  • The distinction between forces above and below the mean is critical for understanding granular mechanics.
  • A new model enables accurate contact force computation in static granular packings.
