Overview

A Landau-type formulation reveals stability of saturated granular packings, suggesting implications for liquefaction phenomena.

Key Points

  • The study aims to formulate the stability of saturated granular packings using static enthalpy equilibrium concepts.
  • Developed a Landau-type framework describing stability through an effective energy landscape.
  • Identified porosity as a macroscopic order parameter influencing structural stability.
  • Analyzed the relationship between structural resistance of grain contacts and buoyancy-reduced gravitational energy.
  • Established a connection between liquefaction phenomena and concepts of metastability in granular systems.
  • Showed that instability occurs when the curvature of the energy landscape vanishes.
  • Described stable granular skeletons as metastable minima in the energy landscape.
