Scope Hexagonal close-packed (HCP) materials, which often serve as structural materials, are complex because they have relatively low crystal symmetry (compared with cubic materials), and depend on both twinning and slip for ductility. Twinning, in particular, is an important aspect of plasticity in hexagonal materials, but the underlying mechanisms for twin nucleation, growth, and interaction with dislocations are still not completely understood. For this reason, the thorough understanding, and subsequent modeling, of mechanical behavior in hexagonal systems is often challenging. This symposium will focus on the structure-property relationships unique to HCP materials. The necessary interplay between experiments and modeling/simulation to understand the plasticity mechanisms and to develop accurate predictive models will be explored. Special emphasis will be placed on works that connect experimental observations with modeling of mechanical behavior across various length scales.
Session topics include, but are not limited to:
- Microstructural observations (including dislocations, twins, grain and twin boundaries) used to validate or direct modeling efforts
- Mechanical behavior of HCP materials, especially twinning mechanisms and phase transformations, and their contributions to plasticity
- Multiscale modeling and simulation of plastic deformation in HCP materials, including micromechanical and continuum plasticity laws based on nanoscale mechanisms
