Below are some areas that I believe will be particularly fruitful and significant to pursue in the next decade:
- MD, discrete dislocation, and crystal plasticity studies of yield criteria and flow
- More complete linkage of discrete dislocation theory and Nye tensor concepts to continuum field models, addressing long range defect field interactions
- Statistical micromechanics
- Superposition of electron backscatter images with simulated fields of view for cyclic and monotonic plasticity
- Origins of scale effects, including statistical inhomogeneity and configurational effects
- Statistical micromechanics
- Accelerated MD, coarse-grained MD, and coupled MD-continuum methods
- Homogenization and localization concepts for evolving hierarchical, heterogeneous microstructures
- Self-organization and scaling laws in grain subdivision, slip and damage evolution in single crystals and polycrystals
- Multiscale nature of the multiplicative decomposition of the deformation gradient and defect field mechanics
- The role of grain boundaries in polycrystals, with explicit accountance in multiscale modeling and crystal plasticity
- Plasticity in materials design
