Webinar: Material-Modeling Support for PFC
DETAILS AND DESCRIPTION
The material-modeling support package for PFC is a collection of geometric shapes in which PFC materials can be created. The materials include three types of bonded materials and two types of granular materials. The bonded materials are instances of bonded-particle models (Potyondy, 2015) that represent a solid as a bonded collection of grains with mechanical behavior that ranges from that of a solid material (such as rock), where the bonds are intact, to that of a granular material, where the bonds have all broken. The grain-size distribution is specified with circular/spherical or clump grain shapes. A material-genesis procedure creates a well-connected and isotropic grain assembly. The material can then be used for boundary-value models (such as the rock-cutting application shown in Fig. 1), or it can be subjected to material tests that include compression, diametral compression, and direct tension (see Fig. 2). The material tests are used to measure macroscopic properties for a calibration process in which the model microproperties are chosen to match a relevant set of microproperties. The 1-hour webinar combines a brief lecture with hands-on model manipulation to demonstrate usage of the material-modeling support package.

The mathematical modeling of physical phenomena is the driving passion for the research of David Potyondy, who has expertise in Computational Structural Mechanics, with a focus on simulating damage processes. Dr. Potyondy obtained his Ph.D. in 1993 in Civil Engineering from Cornell University. He is a research scientist and software developer for Itasca Consulting Group (1994–2003 and 2005–present) and was an Assistant Professor in the Department of Civil Engineering at the University of Toronto during the 2004–2005 academic year. Dr. Potyondy has directed the development of, and has conducted 37 training courses for, the Particle Flow Codes (PFC2D and PFC3D). His research focuses on micromechanical modeling of geomaterials using discrete-element methods in which the material is represented as a bonded collection of discrete bodies. Dr. Potyondy received the American Rock Mechanics Association 2005 Award for Research in Rock Mechanics for his contributions to the development of the bonded-particle modeling methodology.
The webinar will be of interest to PFC users who are constructing bonded-particle models, and those wishing to perform standard rock-mechanics material tests upon the PFC synthetic material.
