Simple hyperbolic soil model

Webb6 mars 2024 · The hyperbolic function proposed by Abbo–Sloan was employed not only to approach the Mohr–Coulomb criterion but also to express the plastic potential function. A better approximation to the Mohr–Coulomb yield and potential surfaces was achieved by increasing the transition angle and proven to be highly efficient in numerical convergence. Webb7- Duncan-Chang Hyperbolic Material Model The mechanical behavior of soils is highly nonlinear and their exhibit stress dependency in their stiffness. The Duncan -Chang model (Duncan and Chang, 1970) is a model developed to address these characteristics. There are more advanced models that are based on the theory of elasto-plasticity that can ...

Webb1 apr. 2024 · In general, soil constitutive models fall under three categories: The first category is simple elastic-perfectly plastic models. In elastic-perfectly plastic models, the initial loading curve follows Hooke’s law up to the yield stress. At yield, the soil obeys a yield criterion, e.g. Mohr-Coulomb. WebbThe Hardening Soil (HS) model (Schanz et al., 1999), or even better, the HS model with small-strain stiffness (HSsmall) (Benz, 2007) includes several features of soil behavior that are relevant for many practical applications, such as: Stress-dependency of stiffness and strength Strain-dependency of stiffness (modulus reduction)

Webb2 dec. 2024 · The equivalence here is with hyperbolic soil models. Although the hyperbolic soil model is probably the most accurate model currently in use, it is not universal with all soils.
