The last thirty years has seen a surge of interest in the development of these methods, especially for crystalline materials, and even a thorough mathematical understanding of these methods has begun to emerge in the last five years.\u00a0 However, the applicability of these methods to crystalline materials has often been restricted only to materials comprised of a Bravais lattice.\u00a0 In this talk, we will present the\u00a0blended force-based quasicontinuum method for\u00a0modeling defects in multilattices, which allows for technologically important materials such as alloys and graphene to be modeled.\u00a0 Error estimates in terms of the computational cost of implementing the method will also be discussed.\u00a0 This is joint work with Xingjie <span class=\"il\">Li<\/span>, Christoph Ortner, and Mitchell Luskin.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Derek Olson,\u00a0Department of Mathematics, University of Minnesota Title: Blended-force based quasicontinuum method for multilattices Abstract:\u00a0Atomistic-to-continuum (AtC) methods are a vast class of multiphysics models which couple atomistic models of materials, such as molecular statics or molecular dynamics, with continuum mechanics models, such as nonlinear elasticity.
