Quick access FABER (Fatigue Benchmark Repository)AnnotationProgress in computational fatigue analysis is hindered by siloed stakeholder research. The current landscape is riddled with fragmented data and limited cooperation. Research is gathering dust and commercial competition is stifling innovation. The FABER Network addresses these barriers and works towards a more open-minded science in engineering and research concerning fatigue life estimation. Are you ready to rise to the challenge? Join the collaboration revolution and become a pioneer in the future of fatigue analysis! State of the artMetal fatigue is a major concern in engineering as it weakens metal components over time. It occurs due to repeated stresses, even if those stresses are below the metal's apparent breaking point. Predicting fatigue is difficult and such process relies on complex calculations or expensive testing. Engineers use computer models to assess fatigue risk in designs, but these models may not be entirely accurate. There's a push for better methods to estimate fatigue so that safer and cheaper designs can be made. Fatigue solvers are software tools built to reduce design costs and time. However, the core methods used in these solvers have not significantly improved in decades, hindered by the prioritization of speed and marketability over accuracy. Developers tend to downplay the need for fatigue expertise and avoid independent evaluation of their software's effectiveness by a limiting end user license agreement. This lack of focus on improvement may well hinder advancements in fatigue estimation. The question is, how can a user test the correctness of a fatigue solver? The FABER project proposes the creation of robust benchmarks for fatigue data to enable better fatigue estimation methods and ultimately lead to safer and more cost-effective designs. StakeholdersFABER concerns a challenge in the engineering field related to fatigue analysis of materials. There are three main stakeholders involved:
There is a lack of robust and affordable ways to verify the accuracy of fatigue solver software. This is leading to a situation where none of the stakeholders are taking full responsibility for ensuring the reliability of fatigue analysis methods. ObjectivesThe overall goal of this project is to improve fatigue analysis methods by creating a central resource for data and tools.This will be achieved through several objectives:
Overall, the project aims to create a more efficient and reliable fatigue analysis process by establishing a central resource for data and tools, fostering collaboration between stakeholders, and promoting the use of standardized practices. COSTThis shortened information is related to the upcoming COST Action “Fatigue Benchmark Repository”, which is negotiated to be supported by COST (European Cooperation in Science and Technology) from November 2024 for 4 years. COST is funding agency for research and innovation networks. Its Actions help connect research initiatives across Europe and enable scientists to grow their ideas by sharing them with their peers. This boosts their research career and innovation. COST is focused on networking support only.

It is practical to to join our mail list (note that this is a different mail list than the mail list used for the WCFA workskhops and PragTic-related activities) to get the first hand information: FABESTFABEST is a spin-off activity of FABER. Originally, it is intended to be a worldwide challenge to provide the best possible fatigue prediction for the provided test setup. It is expected to run twice during the FABER 4-year duration. However, as FABER had not been accepted for a long time, we decided to proceed at a quicker pace and have already started the testing activity. We managed to purchase 1.4 tons of 42CrMo4+QT steel from one heat in the form of bars with a 35 mm diameter. Since FABER will not provide any funding eligible for the experimental effort, the rules for joining FABEST are as follows:
