Scientific Abstract

An extended DEM approach with multi-scale aggregates and healing algorithms will be used to study structures on the grain and single-band scale, whereas the reservoir scale flow properties will be determined with continuum models. Codes will be developed and tested simultaneously and natural examples from our rock collection and field examples can be used in the other projects. We will then develop an algorithm for the healing of fractured grains and will finally approach the large scale and look at the influence of deformation bands on the permeability of aquifers. Here we will vary mechanical content in bands, deformation conditions from shear to compaction, compactional and extensional shear, and finite strain.
