  • Reliability assessment of flexural fatigue failure of

    Oct 10, 2020 · The traditional reliability theory revolving around sudden failure is obviously not conductive to the understanding and characterization of failure laws for asphalt pavement. It would be, therefore, imperfect to only conduct the reliability assessment in the design period without the consideration of pavement performance degradation.

  • Analysing fatigue and preventing fatigue - AES Reliability

    Analysing fatigue and preventing fatigue failures. On March 27th 1980, the Alexander Keilland oil rig, operating in the North Sea's Ekofisk field, broke up and capsized with the tragic loss of 123 lives. Subsequent investigations showed that the disaster had been caused by fatigue cracks emanating from an apparently innocent small hydro phone

  • 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.
