GB/T 15248-1994 Axial constant amplitude low cycle fatigue test method for metallic materials

This standard specifies the definition of terms, specimen preparation, equipment, test procedures, result processing and test report for axial constant amplitude low cycle fatigue test of metallic materials. This standard is applicable to low cycle fatigue test of metallic materials with equal cross-section and funnel-shaped specimens under axial constant amplitude tensile-compressive stress or continuous change of strain, excluding the test of full-size components and structural parts. This standard is applicable to the test at temperature and strain rate where the time-dependent inelastic strain and the time-independent inelastic strain are negligibly small. The inelastic strain referred to here refers to all inelastic strains. This standard allows the test to be carried out under environmental factors such as temperature, pressure, temperature, medium, etc., but these factors should remain constant during the entire test process. This standard can be used as a guide for low cycle fatigue test in material development, mechanical design, process and quality control, product performance determination and failure analysis.
