The database contains 272 fatigue datasets of S- N (the stress-life relation), ε- N (the strain-life relation), and d a/d N-Δ K (the relation between the fatigue crack growth rate and the stress intensity factor range) data, together with the information of materials, processing and testing conditions, and mechanical properties.
Automatic extraction and manual examination are combined in the workflow to improve the efficiency of processing, the quality of published data, and the reusability. Data for both metallic glasses and multi-principal element alloys are included and analyzed for their statistics and patterns. A fatigue database (FatigueData-CMA2022) is compiled from the literature by the end of 2022. The past few decades have witnessed rapid progresses in the research and development of complex metallic alloys such as metallic glasses and multi-principal element alloys, which offer new solutions to tackle engineering problems of materials such as the strength-toughness conflict and deployment in harsh environments and/or for long-term service.
