Atomistic simulations of dislocations and defects

This paper reviews selected recent research on the atomistic simulation of dislocation and defect properties of materials relevant to the multiscale modeling of plasticity and strength, with special emphasis on bcc metals and including work at extreme conditions. Current topics discussed include elasticity and ideal strength, dislocation structure and mobility, grain boundaries, point defects, and rapid resolidification, as well as noteworthy examples of research that directly impacts the issue of linking of length and/or time scales, as required in multiscale materials modeling. The work reviewed has been inspired by the recent international Workshop on Multiscale Modeling of Materials Strength and Failure held in October 2001 at Bodega Bay, California. This revised version was published online in June 2006 with corrections to the Cover Date.
