ActiveMetallic materials—Determination of residual stress—Sectioning relaxation strain-gage method
金属材料 残余应力测定 全释放应变法
Application Summary AI generated
This standard specifies the method for determining residual stress in metallic materials using the sectioning relaxation strain-gage technique. It is applied in engineering and manufacturing contexts, such as quality control of welded structures, machined components, and heat-treated parts, to measure internal stresses that affect material performance and structural integrity. The method is particularly relevant for industries like aerospace, automotive, and heavy machinery where precise stress analysis is critical for preventing failure.
