Presentation Transcript


1. Geotechnical modelling and critical state soil mechanics Naples, May 2007 David Muir Wood University of Bristol

6. yield loci for natural clays

7. typical experimental observation: stiffness falls steadily with monotonic straining: is there an elastic region?

8. how do we objectively identify yielding? occurrence of irrecoverable strain? dissipation of energy in loading/unloading cycles? change in slope of stress:strain response?

10. kaolin revisited: isotropic consolidation histories

11. kaolin revisited: one-dimensional consolidation histories

13. Deviatoric stress response envelopes
