摘要

The technical communities of solid mechanics, mechanical engineering, computational mechanics, and materials science and engineering invest significant effort to develop physically-based models of material plasticity. However, a comprehensive macroscopic model based entirely on the unit mechanisms at microscopic scales remains elusive, especially for crystalline solids. Internationally, researchers have recently begun to build a new framework for crystal plasticity based on the statistical mechanics of dislocation motion and coarse graining of dislocation ensemble effects. We have assembled a viewpoint set that describes recent advances in theory, modeling and experiments, to which this article serves as an introduction.
