Outline:
Within this project the fatigue strength of thick-walled load-bearing structures will be investigated. Applications are first and foremost support structures for offshore wind power plants. The aim is to include all phases of crack initiation and propagation in the life cycle assessment in combination with a local approach to fatigue. The potentials of modern manufacturing methods and post processing techniques of welds shall be exploited. This procedure is currently not possible under the existing rules and guidelines like Eurocode and IIW partly due to the lack of full-scale trials for validation. Therefore, also the scalability of small-scale trials will be investigated.
The project outcome will be recommendations to update current rules and guidelines in offshore industries as well as for other industries.
The project is part of the overall project SMATRA.
