Einige Animationen:

• 3D view of the Normal Compression Line (NCL), Critical State Line (CSL) and State Boundary Surface of the MCC model 
• Mohr-Coulomb hexagon and stress invariants 
  
• Modified Cam Clay model:
  • conventional undrained test of an initially normally consolidated clay
  • conventional undrained test of an initially slightly overconsolidated clay
  • conventional undrained test of an initially highly overconsolidated clay

• How does ν affect the stress path of a plane-strain compression test and the Lode angle at failure? linear-elastic, ideal-plastic with failure according to Mohr-Coulomb (φ = 30°, c = 0, ψ=0)
• How does ν affect the K₀-stress path (the stress path under oedometric compression). Here shown for the linear-elastic model, Mohr-Coulomb hexagon for φ = 30°, c = 0 is added; inspired by Zheng; Liu & Li (2005): doi: 10.1002/nme.1406
