Multiscale modelling

Material properties emerge from phenomena on scales ranging from angstroms to meters. Only a multiscale treatment can provide a basis for an understanding of material behavior on different scales. The traditional multiscale approach couples two models operating at different scales. An alternative modelling strategy, called Peridynamics, is to continualize the molecular dynamic models, thus replacing inhomogeneities present on smaller length scales by an enhanced continuum description on larger length scales resulting in a nonlocal reformulation of continuum mechanics. Peridynamics is a single multiscale model valid over wide range of length scales and can be considered as an upscaling of molecular dynamics. Our research is focused on simulation on both nanoscale and macroscale and development of peridynamic models.
