Simple hyperbolic soil model
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) High normal stress causes strain hardening at the soil-structure interface during shearing. Therefore, the regressed shear stress-displacement relationship is hyperbolic as demonstrated by monotonous shear (Acar et al. 1982) tests on quartz sand in contact with steel, wood, and concrete. Normal stress and … Visa mer Quasi-linear models were used by Goodman (Goodman et al. 1968) and Desai (Desai et al. 1986); the example in (Jong et al. 2024) calibrated to the Mohr-Coulomb model and … Visa mer Shear stress and interface displacement are described by a higher function. A new model for axisymmetric interfaces (Heuze and Barbour 1982), such as footing designs and a model capturing rock joint dilatant effects, are … Visa mer The state model parameters described the suction-dependent CSL that enables both the plastic hardening module and dilatancy, which … Visa mer The creeping response of thin-layer, “virtual” thickness and solid interface parts is investigated (Karabatakis and Hatzigogos 2002).
