This talk covers a variety of different aspects relevant for the numerical modelling of pile installation processes in a continuum mechanics framework. Lagrangian and Eulerian schemes to discretise the soil are discussed and various hydro-mechanically coupled finite element formulations are inspected for their suitability for application to vibratory pile driving in water-saturated soil. Two different mortar contact discretisation techniques are presented and a new framework for the formulation of constitutive interface models based on constitutive continuum models is introduced. Finally, the application of the numerical schemes to the simulation of the installation of offshore piles is presented.
Dr. Staubach has been an Interim Professor and Chair of Geotechnics at Bauhaus Universität Weimar,Germany since 2023. He has also been a Researcher and Chair of Soil Mechanics at Ruhr-Universität Bochum, Germany since 2020. He was a Researcher and Chair of Geotechnics at Bauhaus Universität Weimar from 2018-2022 and a Researcher at Institute of Soil Mechanics and Rock Mechanics,Karlsruhe Institute ofTechnology from 2018-2019. He obtained his first two degrees in 2016 and 2018 respectively, both from KIT, and his PhD from Ruhr-Universität Bochum in 2022, awarded with highest distinction (summa cum laude).
