Offshore Foundation

Numerical simulations of Offshore Foundations using the modified Cam-Clay model and the hyperplasticity theory.

 

This project aims to build advanced numerical procedures using 3D smoothed particle FEM to study Offshore Engineering, including Offshore foundations and pipelines and a particular emphasis is placed on Sea Waves. The use of “the modified Cam-Clay model” and “the hyperplasticity theory” is firmly established in the analyses. We focus on the development of practical models for cyclic loading based on the simplified kinematic hardening plasticity framework (Krabbenhøft and Krabbenhøft, 2021) and implement these simplified models into the Optum CE. Validation analyses and parametric studies will be used to incorporate the stochastic spatial variability of soil properties within the advanced numerical analyses.
