The numerical modeling of swelling strain and swelling pressure of expansive soils when saturated with a unique set of material parameters is still a challenge that persists to this day. In collaboration with BTU Cottbus and Ruhr University Bochum, we have developed a new hypoplastic model for expansive soils. In our latest publication in the journal Bautechnik, we validate this model by back-calculating numerous laboratory tests and introduce a simplified calibration procedure.
In our latest paper in Bautechnik, we address two challenging topics: the automatic calibration of advanced constitutive models and the significance of the constitutive contact model in realistically simulating soil-structure interaction. Automatic Calibration & Slopes Read more…
In our latest paper published in Comput. Methods Appl. Mech. Engrg we present a mortar contact discretization scheme enforcing contact constraints separately for the pore fluid and the solid.
