GB/T 26076-2010Metal sheets and strips - Axial-force-controlled fatigue testing method (English PDF)

1 Scope

This standard specifies the metal sheet (strip) samples at room temperature (without introducing stress concentration) axial force control terms and definitions fatigue test,

Sample, test conditions, test procedures, and test results are shown reports.

This standard applies to a thickness of 0.3mm ~ 3mm sheet metal (with) a sample (not including notched specimens) bear either shown in Figure 1

Type constant axial load stress amplitude cyclic fatigue tests; minimum cross-sectional area of the sample rectangular cross-section less than 30mm2.

sigmam --- mean stress;

sigmaa --- stress amplitude;

R --- stress ratio.

Type 1 cyclic stress
