Title: Peridynamics: A Framework for Fracture, Multiscale, and Complex Materials Modeling
Abstract: Fracture prediction as well as computational modeling of mutiscale and other complex materials behavior are ongoing challenges in materials science and computational science and engineering. Peridynamics offers a new framework to overcome these challenges through governing equations that naturally represent material discontinuities, introduce length scales, and allow for general constitutive relations. Peridynamics is a nonlocal reformulation of classical continuum mechanics suitable for material failure and damage simulation. In this presentation, we will provide an overview of peridynamics and illustrate some of its capabilities in scale-bridging and modeling of anisotropic media.
