Plasticity from the Atomic Scale to Constitutive Laws

These papers are based on presentations prepared for the symposium Plasticity from the Atomic Scale to Constitutive Laws.

The original symposium description is as follows: "Recent developments in computational and experimental Material Science have enhanced our ability to model and measure fundamental aspects of plastic deformation.

Advances in high performance computers and improvements in atom scale modeling, dislocation dynamics, and meso-scopic simulations are allowing studies at larger length and longer temporal scales.

Simultaneously advances in experimental methods are producing measurements of mechanical response at increasingly smaller length scales, while improved characterization methods (using electrons, X-rays, neutrons, non-linear elastic response and acoustic emission) are providing new insights into deformation processes at atomic through to inter-granular length scales".The original symposium description is also as follows: "As the mechanisms operating across these various scales are better understood and quantified adaptive, physics based constitutive laws should be possible. This symposium encompasses novel experimental and simulation methods exploring the individual or collective evolution of dislocations in metals.

The topics include, but are not limited to: modeling and experimental characterization of isolated dislocations, dislocation-defect interactions, dislocation ensembles, and informed single crystal constitutive laws.

Focus applications include solid solution effects, size effects, work hardening, and rate limiting behavior in single and multi-phase materials."
