Scope

This guiding technical document specifies the data requirements for new materials and allowable room temperature strength design values, high and low temperature static mechanical properties, typical stress-strain curves and full stress-strain curves, endurance and creep strength, high cycle fatigue ( Processing and expression of data such as stress fatigue), low-cycle fatigue (strain fatigue), fatigue crack growth rate, fracture toughness, etc., as well as commonly used mathematical statistical methods. This guiding technical document is suitable for judging whether the mechanical properties data of metal materials used in aviation and spacecraft structures are accurate and reliable, and determining whether various performance data can be provided for use (such as various metal material data manuals, compilations and special technologies for design use The minimum data requirements and analysis and processing methods for reports, etc.) can also be applied to the analysis and processing of material data for other structures. Other well-founded analysis and processing methods can also be used for data processing and expression of mechanical properties of metal materials, but this should be explained when expressing the data.
