Atomistic and continuum modeling of dendritic solidification

Due to its technological importance, modeling of dendrite growth in pure metals and alloys remains a significant challenge in the field of materials science. In this review recent achievements in the dendrite modeling problem, using two distinct length scale approaches, are summarized. At the nanometer scale, molecular dynamics and Monte Carlo techniques have been developed to extract two impor...

Adaptive Atomistic-continuum Modeling of Defect Interaction with the Debdm

New procedures for modeling interactions among dislocations and nanosized cracks within the dynamically evolving bridging domain method (DEBDM) have been developed. The DEBDM is an efficient concurrent atomistic-tocontinuum approach based on the bridging domain method, where the atomic domain dynamically adapts to encompass evolving defects. New algorithms for identifying and coarse graining di...

Matching conditions in atomistic-continuum modeling of materials.

A new class of matching conditions between the atomistic and continuum regions is presented for the multiscale modeling of crystals. They ensure the accurate passage of large scale information between the atomistic and continuum regions and at the same time minimize the reflection of phonons at the interface. These matching conditions can be made adaptive if we choose appropriate weight functio...

On Atomistic-to-Continuum Coupling by Blending

A mathematical framework for the coupling of atomistic and continuum models by blending them over a subdomain subject to a constraint is developed. Using the framework, four classes of atomistic-to-continuum (AtC) blending methods are established, their consistency is studied, and their relative merits are discussed. In addition, the framework helps clarify the origin of ghost forces and formal...

Researchers Discuss Atomistic-to-Continuum (AtC) Coupling

On March 20, 2006, researchers from around the world gathered in Albuquerque, New Mexico, for a two-day workshop on atomistic-to-continuum (AtC) coupling analysis. The Computer Science Research Institute at Sandia National Laboratories sponsored the workshop, which was organized by Claude Le Bris (École Nationale des Ponts et Chaussées), Jacob Fish (Rensselaer Polytechnic Institute), and Pavel ...
