Isotropic Elastic Behaviour

  • Alexander M. Puzrin


For a slightly overconsolidated clay sample, in the initial part of a triaxial compression stress path, the sample behaviour may be assumed reversible for both its deviatoric (Figure 10.1a) and volumetric (Figure 10.1b) components. This means, that before the stress path reaches the yield stress state \(Y({{{p}'}_{y}},{{q}_{y}})\), the unloading stress-strain curves will approximately follow the corresponding loading curves, and no residual strain will appear in a closed loading cycle.
