3D Behavior of Sand Particles Using X-Ray Synchrotron Micro-Tomography
Granular materials are composed of discrete particles in contact with each other. At the micro scale, each particle is in contact with neighboring particles where individual particle properties and contact mechanics govern particle interaction. At the meso scale, multiparticle assemblies interact through contact networks at particle contact. In this paper, synchrotron X-ray micro-tomography (SMT) is used to study particle kinematic behavior during in situ axisymmetric triaxial testing. High-resolution SMT images are used to discretize and track individual particles at multiple SMT-imaging stages of axisymmetric triaxial experiment. A particle-tracking algorithm, similar to digital image correlation, was developed by the authors to track individual particles throughout the entire test, and particle kinematics are quantified at each imaging stage. The algorithm allows tracking of individual particles and quantifies the relative (between images) and absolute (total) translation and rotation of particles as the test progresses.
