In granular materials, most particles carry less than average load. A new method objectively quantifies force chains, revealing that about half of strong network particles form these chains, which decrease in number as deformation increases.

Area of Science:

  • Physics
  • Engineering
  • Materials Science

Background:

  • Granular materials exhibit heterogeneous load distribution, with most particles carrying below average.
  • Above-average load-bearing particles form a strong force network, distinct from the weak network of the majority.
  • Force chains, quasilinear arrangements of particles, are hypothesized to transmit strong forces and correlate with principal stress trajectories.

Purpose of the Study:

  • To develop an objective procedure for quantifying force chain statistics in granular materials.
  • To define force chains based on particle arrangement and stress concentration.
  • To analyze force chain behavior during granular material deformation.

Main Methods:

  • A two-part definition of force chains was proposed: quasilinear arrangement of >=3 particles and stress concentration along the chain.

  • An algorithm was developed to implement this definition and compile force chain statistics.
  • The algorithm was applied to a discrete element simulation of a rigid punch indenting a granular half-space.

    • Main Results:

    • Approximately 50% of particles in the strong force network were identified as part of force chains.
    • The number of force chains decreased as the punch advanced into the granular material.
    • Force chain lengths were found to follow an exponential distribution, with average length varying slightly during deformation.

    Conclusions:

    • The developed procedure provides a quantitative tool for analyzing force chains in granular media.
    • The study highlights the importance of force chains in understanding granular material behavior.
    • Future research should focus on incorporating force chain branching into the analysis.
