USNCCM-11 Minisymposium: Recent Advances in Nonlocal Computational Mechanics

11th US National Congress on Computational Mechanics

July 25-29, 2011. Minneapolis, MN

A mini-symposium on Recent Advances in Nonlocal Computational Mechanics

Abstract submission deadline: January 31, 2011 (minisymposium 3.3)

Summary

This symposium will highlight recent theoretical and algorithmic developments in nonlocal methods for
computational mechanics. Nonlocal methods, such as gradient and integral methods, offer alternative approaches
that avoid difficulties arising in local theories. Such difficulties frequently arise in, among others, fracture and
failure modeling, coupled multi-physics problems, inelasticity, and problems involving material instabilities and
discontinuities. Nonlocal regularization, for example, has been shown to remove the mesh dependence of local
solutions. Although many nonlocal models have been developed in the past, the application of these methods for
modeling and simulation has not reached its full potential. This symposium invites contributions on methods in
computational mechanics with an emphasis on extensions of the classical theory that incorporate nonlocality.

Target areas

-Nonlocal gradient and integral models for fracture and failure

-Peridynamics

-Gradient inelasticity
