Abstract
Four materials modeling and simulation topics have been reviewed. Dislocation modeling shows significant progress in using the results of atomistic dislocation interaction calculations as input to discrete dislocation models, which, in turn, are now able to predict stress–strain relationships. Atomistic models have now been used to predict dynamic and microstructural effects on fracture. Continuum solidification models are now able to predict microstructural features. Plasticity models have been formulated that include dislocation and grain size distributions.
