Image Analysis for Interparticle Contact Modeling

by Samuel G. Paikowsky, Univ of Massachusetts at Lowell, Lowell, United States,

Document Type: Proceeding Paper

Part of: Digital Image Processing: Techniques and Applications in Civil Engineering

Abstract:

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 analysis 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 techniques used for the measurements are described and evaluated.
