Image Analysis of Interparticle Contact Modeling

Two dimensional photoelastic elements (disks or ellipses) are used as models for studying granular material behavior. The required observations include accurate continuous measurements of the interparticle forces (magnitude and orientation) during motion. Different methods of analyses were developed based on the isochromatic fringe pattern around the contact point. An image processing and analysis system was set to enable the measurements of the required isochromatic fringes. The system and technique used for the measurements are described and evaluated in this paper.
