The project SIMCOFAT addresses a fundamental challenge in materials engineering, namely the reliable prediction of corrosion-fatigue cracking in critical structures and components. Corrosion-fatigue is a complex phenomenon that occurs when materials, often used in demanding environments such as offshore wind turbines and aerospace components, are subjected to cyclic loading in the presence of corrosive agents. The combined action of mechanical stress and environmental degradation can lead to crack initiation and propagation, and ultimately the failure of the integrity and safety of structures. In this context, the overall objective of the project is to develop a comprehensive numerical framework that can predict corrosion-fatigue damage and crack propagation, incorporating microstructural information and environmental factors. This framework is expected to offer a paradigm shift in the field of corrosion science, promising more accurate, informed, and cost-effective strategies for the management and maintenance of critical infrastructure.
The specific objectives of the project can be summarized as follows (1) To develop advanced multiscale modelling tools capable of capturing the microstructural factors that affect corrosion-fatigue behaviour. By integrating microstructural information, such as grain boundaries and material properties, into the modelling process, this project aims to provide a more accurate representation of real-world corrosion-fatigue phenomena. (2) To create a numerical framework that seamlessly integrates fatigue and corrosion models. By linking these two phenomena, we aim to provide a more complete understanding of how corrosion processes interact with mechanical fatigue, ultimately leading to crack initiation and propagation.
In summary, this project is driven by a profound need for advanced tools to predict and mitigate the effects of corrosion-fatigue on critical structures. It combines state-of-the-art modelling techniques, real-world validation, and broad impact to provide a holistic solution to the challenge of corrosion fatigue.
