The use of advanced numerical methods to analyse the performance of offshore wind turbines (OWTs) under environmental loads led recently to improved design methodologies [1] that reduce the construction cost significantly. However, the accurate OWT-monopile-soil interaction modelling is still an ongoing research challenge, mainly due to the lack of a well-established theory for the mechanical response of soils under generalised loading conditions [2].
The aim of the project is the development of a novel constitutive framework that includes the complexity of soil’s microstructure (fabric) and its effect on soil’s mechanical response during generalised cyclic loading. The model will be applied in high-fidelity, 3D, hydro-mechanically coupled FE analysis of OWT-monopile-soil interaction, for a more accurate analysis of the long-term performance of OWTs, that can lead to a more cost-effective design practice.
