  • Statistical analysis of fatigue test data - TWI

    Fatigue test data produced at low stress ranges has inherently more scatter because fatigue cracking is dominated by crack initiation [] and so is less suitable for regression analysis as it will skew the value of slope from the regression results. Therefore, stress ranges should be chosen to produce lives in the range 10,000 to 1,000,000 cycles.
