Abstract

By employing a mortar-type contact algorithm, we develop a theoretical and numerical framework for elastoplastic interaction of unsaturated granular soils with a rigid cylindrical object in both static and dynamic analyses. The elastoplastic response is modelled with a constitutive model based on the effective stress concept for unsaturated soils. The constitutive model offers the ability to simulate the effect of stress-induced anisotropy on the plastic response. Several numerical examples are provided for verification purposes and sensitivity analysis, demonstrating the capabilities of the presented framework.
