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. Webb3 aug. 2024 · Accordingly, the hyperbolic model was used to simulate the soil-geosynthetic interface behaviour. Moreover, a three-dimensional finite element model of the direct …
WebbThe method simulates the connection of the soil with the walls with non-linear elastoplastic Winkler springs. The soil springs receive their initial properties from the at-rest situation … Webbmodels like those belonging to the family of hyperbolic soil models are often used and implemented in well-known nonlinear codes such as DEEPSOIL [8] and DMOD2000 [9]. The use of hyperbolic models involves several issues: the analytical model for the skeleton curve, criteria for loading-
