Modified cam clay version with const E: clean-up, bug-fix, renaming
Changes
- 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)
Fixes
- workaround for state variable initialization in MFront removed
- bugfix algorithmic tangent, only relevant for theta<1
