Description

The symposium is intended to establish connections between microstructural and statistical properties of dislocation defects with macroscopic crystal plasticity. Many aspects of crystalline plasticity have been found to exhibit stochastic or scale-free properties (examples include strain burst statistics, dislocation patterns, crack nucleation), yet, neither the origin nor the consequences of such behaviour are fully understood. To facilitate development in this long-standing issue, this interdisciplinary symposium will bring together researchers of various subfields of materials research. In addition to reviewing current developments in dislocation plasticity the focus will be concentrated on insights that may originate in various modeling approaches, that may also be utilized in other frustrated models of statistical mechanics, such as jamming of spheres or polymers. Emphasis will be given to amorphous materials, too, where unique tools have been proposed to link micro and meso scales. Comparing up-to-date theoretical techniques and methods of experimentation on these fields shall inspire ideas for future work on both modeling and experiments in crystalline and amorphous systems, as well as other sub-fields.
