For the computational modelling of rock behavior, modern personal computers and parallel computers are available.
A series of program systems with respect to continuum and discontinuum mechanics is used, which allow the evaluation of planar and three-dimensional problems under statical and dynamical loading conditions:
- FLAC, FLAC3D , UDEC, 3DEC, PFC2D and PFC3D from ITASCA, with constitutive equations which were developed
by IfG for special geomechanical problems and implemented in the source code of the programs:
- elasto-plastic material model to describe the softening and brittle fracture behavior of carnallite
- visco-elastoplastic material model with softening, dilatancy and (primary, secondary and tertiary) creep to describe the time-dependent softening behavior of salt rocks preceding creep fracture
- combined material model for describing the creep of salt rocks, including inverse transient creep
- MKEN, SENK - programs developed by IfG for the computation of time-dependent stress-strain processes in a system of underground openings and for the prediction for surface effects resulting from mine subsidence.
