Thanks to our close ties with the rock mechanics laboratory and field measurements, we can obtain location-specific input parameters for our models, such as strength and creep rates, and adapt them to real-world behavior. The models are thus able to provide reliable predictions even for complex mining situations, for example, regarding strength and creep behavior under a wide range of stress and temperature conditions as well as under cyclic loading.

The images show, as an example, the recalculation of seven triaxial strength tests using the extended strain hardening approach (IfG-GS) and a uniform set of parameters. Left: strength, right: dilatancy, each as a function of axial deformation.
