Scope This symposium will provide a platform for researchers working on the state-of-the-art of multiscale modeling of materials, microstructural characterization, and small-scale mechanical testing to understand the mechanical behavior of crystalline metals.

Background and Rationale: The mechanical behavior of crystalline metals strongly depends on microstructure and the evolution of microstructure at different length scales. Examples include changes in crystallography, defect content and distribution, grain morphology, interfaces, and texture. The success behind the development of multiscale predictive model relies on finding and exploiting the synergies between modeling and experiments. In recent years intense efforts have been dedicated to advancing atomistic, micro, meso and macro-scale simulations tools and bridging them to understand the structure-property relationship. Achieving this goal requires a strong connection between models and experimental characterization techniques at different length scales. This symposium aims to encourage scientists/researchers from diverse areas of materials science and engineering to present recent achievements, identify challenges in developing multiscale material models from the atomic scale to the macro scale, and discuss connections with advanced experimental techniques.

The subject areas of the symposium include, but are not limited to:
1. Structural, functional and nuclear materials
2. Dislocations, deformation twins, phase transformation and recrystallization
3. Atomistic modeling
4. Dislocation dynamics and phase field modeling
5. Crystal plasticity models
6. Advanced X-ray and neutron diffraction techniques
7. Advanced microscopy techniques including HR-(S)TEM, HR-EBSD, PED and in-situ TEM and SEM
8. Emphasis on integrating experiments with modeling for guidance/validation
9. Experimentally aided Multi-scale Material Modeling
