Area of Science:

  • Rheology
  • Granular Mechanics
  • Tribology

Background:

  • Granular materials exhibit complex flow behaviors under confinement.
  • Understanding the influence of external factors like velocity and humidity is crucial for predicting material response.

Purpose of the Study:

  • To investigate the rheological properties of granular materials under slow driving in confined geometries.
  • To characterize the transition from steady sliding to stick-slip motion.
  • To develop a model explaining the observed behaviors.

Main Methods:

  • Experimental study of granular material flow in a confined setup.
  • Systematic variation of driving velocity and surrounding relative humidity.
  • Development of a phenomenological model based on friction properties.

Main Results:

  • Observed steady sliding with resistance force proportional to driving velocity and relative humidity.
  • Identified a transition to stick-slip motion at lower velocities, with enhanced blocking as velocity decreases.
  • The proposed model successfully explains the observed velocity and humidity dependencies.

Conclusions:

  • Friction between grains and the boundary is the primary factor governing granular material rheology in this setup.
  • The transition to stick-slip motion is a key feature of granular flow under specific conditions.
  • The developed model provides insights into the mechanics of granular resistance.
