Abstract
Multiscale modeling methods for the analysis of fracture in metallic microstructures are discussed. Molecular dynamics models are used to analyze grain-boundary sliding and fracture in an aluminum bicrystal model. A bilinear traction-displacement relationship that may be embedded into cohesive zone finite elements for microscale problems is extracted from the nanoscale molecular dynamics results.
