Multi-scale techniques and scale bridging play a key role in connecting the macroscopic behaviour of materials directly to the material microstructure and elementary deformation processes. Many different classes of scale bridging methods have been developed for this purpose, from the atoms to the continuum scale. These generally involve multiple disciplines, e.g., engineering, computational mechanics, mathematics, physics, chemistry, and so on.
This session is intended as a forum for bringing together scientists from different disciplines working on multi-scale techniques and scale-bridging problems in mechanics of materials, including both spatial, as well as temporal scales.
The 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 quasi-continuum method)
dislocation Dynamics based methods (e.g. DD-FEM coupling)
embedded domain methods, domain decomposition methods, global-local techniques
heterogeneous multi-scale method (HMM), equation-free method
coarse graining methods
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-mechanical etc.)
model reduction techniques and reduction of computational costs associated with multiscale algorithms
