The search for ideal structural materials has been intimately tied to the history of mankind, sometimes even linked to the rise and fall of civilizations. Design and development of strong materials through microstructural engineering has been at the core of this progress. Recent advances in materials synthesis and characterization techniques coupled with increasing sophistication of computational prowess in materials modeling are expected to enable designing optimal materials for applications that span across a range of temperature-, pressure-, strains-, and rates.
This symposium proposes to bring together researchers in the field of experimental and computational materials mechanics with a focus on understanding the plasticity mechanisms in metallic microstructures subjected to dynamic stimuli that range over several orders of magnitudes. The topics of interest include but not limited to:
- External stimuli – temperature excursion, high strain-rate, diffusion of species;
- Deformation mechanisms – dislocation plasticity, twinning, phase transformation, fracture;
- Modeling and Simulations – first principle, atomistics, dislocation dynamics, crystal plasticity, homogenized continuum methods;
- Experiments – characterization techniques, in-situ TEM, micro-scale testing, high rate techniques.
Of particular interest are studies that bridge between experimental multi-scale characterization and mechanism-based multi-scale models for plasticity at fundamental length-scales.
