Modified cam clay version with const E: clean-up, bug-fix, renaming

Christian Silbermann requested to merge cbsilver/ogs:ModifiedCamClayBasic into master


  • redundancy removed: only volume ratio evolution left, no porosity anymore
  • minimum value for the pre-consolidation pressure introduced => yield surface cannot degenerate to point anymore
  • elasticity tensor inversion simplified (required for consistent initial state with absolute elastic formulation)


  • workaround for state variable initialization in MFront removed
  • bugfix algorithmic tangent, only relevant for theta<1
  1. Feature description was added to the changelog
  2. Tests covering your feature were added?
  3. Any new feature or behavior change was documented?
