ABSTRACT
In the last decades numerous approaches have been developed for establishing the constitutive behavior of rock salt mainly motivated by saltmining industry applications or by the possible use of excavated openings in rock salt formations as repositories for nuclear waste. Here, a detailed description of the advanced strain-hardening model is presented which is based on these physical processes and which describes all three creep phases in the scope of a creep model. It represents the actual state of long-lasting developing work performed by the authors in the recent years (e.g., Salzer 1993, Salzer et al., 1998, 1999, Günther & Salzer 2007, Günther 2009, Günther et al., 2010).
