Webb14 aug. 2013 · The paper investigates the mathematical structure of plasticity models for unsaturated soils and provides a strategy to capture the loss of uniqueness of the incremental solution upon loading and/or wetting paths. To derive bifurcation conditions in simple analytical form, the analysis is restricted to isotropic stress states. WebbThe plasticity modulus is in turn related to the Tangent Modulus and Young’s Modulus (E) as follows: The value of Tangent Modulus is set to 10% of the Young’s Modulus as a default. Thus the default values ensure a 10% slope for the linear plastic part of the material’s stress-strain curve. icac commonwealth
