Abstract

CSMD Seminar Series

Multiscale modeling has been recognized in recent years as an important research field to achieve feasible and accurate predictions of complex systems. Peridynamics, a nonlocal reformulation of continuum mechanics based on integral equations, is able to resolve microscale phenomena at the continuum level. As a nonlocal model, peridynamics possesses a length scale which can be controlled for multiscale modeling. For instance, classical elasticity has been presented as a limiting case of a peridynamic model. In this talk, I will introduce the peridynamics theory and show analytical and numerical connections of peridynamics to molecular dynamics and classical elasticity. I will also present multiscale methods to concurrently couple peridynamics and classical elasticity, demonstrating the capabilities of peridynamics towards multiscale material modeling.

Dr. Seleson is a Postdoctoral Fellow in the Institute for Computational Engineering and Sciences at The University of Texas at Austin. He has obtained his Ph.D. in Computational Science from Florida State University in 2010. He holds a M.S. degree in Physics from the Hebrew University of Jerusalem (2006), and a double B.S. degree in Physics and Philosophy also from the Hebrew University of Jerusalem (2002).
