Porosity and permeability of crushed and damaged rock salt during compaction

In addition, well proven constitutive models are in use to predict to which extent the EDZ and the properties of the damaged rock salt will develop with time (Günther & Salzer 2007, Hampel & Schulze 2007, Hou et al., 2007). This concerns the mechanical weakening with consequences for the strength and strain to failure as well as for the progressive increase in ductility during long-term deformation processes.
