Catalogue of NIMS fatigue data sheets

Area of Science:

• Materials Science
• Mechanical Engineering
• Fatigue Analysis

Background:

• The NIMS fatigue data sheets comprise a vast repository of structural material fatigue properties.
• Understanding material fatigue is critical for structural integrity and component lifespan.

Purpose of the Study:

• To summarize the NIMS fatigue data sheets and provide a new, accessible gateway to this resource.
• To review fundamental fatigue properties, high-temperature behavior, and fatigue in welded joints.

Main Methods:

• Compilation and summarization of existing NIMS fatigue data.
• Analysis of high-cycle, low-cycle, and gigacycle fatigue test results.
• Review of fatigue properties at room and elevated temperatures, and for welded joints.

Main Results:

• The database includes fatigue limits, fatigue lives, and cyclic stress-strain curves for various materials like steels, aluminum, and titanium alloys.
• High-temperature fatigue data, particularly for steels, were evaluated using diverse strain rates and waveforms.
• Fatigue properties of welded joints in steels and aluminum alloys were assessed through high-cycle fatigue and crack propagation tests.

Conclusions:

• The newly accessible gateway facilitates broader use of extensive NIMS fatigue data.
• The reviewed data provide valuable insights into material fatigue behavior under various conditions, including high temperatures and welded configurations.
• New findings from the analysis of this comprehensive fatigue dataset are highlighted.
