Symposium description
Scale bridging and multiscale techniques play a key role in connecting material’s behaviour directly to the material’s microstructure and elementary small-scale processes. Many different classes of scale-bridging methods have been developed for this purpose, from the atomistic to continuum scales. These generally involve multiple disciplines, including engineering science, computational mechanics, materials science, mathematics, physics, chemistry and computational science. This session is intended as a forum for bringing together scientists from different disciplines working on multiscale techniques and scale-bridging problems in the mechanics of materials, including both spatial as well as temporal scales.
Topics to be addressed in this session include (but are not limited to):
• Homogenization-based methods, e.g. mathematical homogenization, computational homogenization etc.
• Atomistic-to-continuum coupling methods (e.g. the quasicontinuum method, coarse-grained density functional theory)
• Dislocation Dynamics-based multiscale methods (e.g. DD-FEM coupling)
• Embedded domain methods, domain decomposition methods, global-local techniques
• Coarse graining methods
• Temporal upscaling and atomic time scale extension techniques
• Methods for phenomena with (partially) non-separating scales, e.g. localization, damage and fracture or transient phenomena
• Methods for coupled multi-field phenomena (e.g. thermo-chemo-electro-magneto-mechanical)
• Model reduction techniques and reduction of computational costs associated with multiscale algorithms
• Techniques for the description of complex microstructures, e.g. arising from experimental imaging techniques
• Data-driven strategies in multiscale modelling
