PROCESS CAPABILITY INDICES FOR FATIGUE LIFE MODEL

Abstract: In time to failure analysis the word ‘fatigue’ commonly depicts a situation that may arise due to shock accumulation or component failures. Factors that produce this adversity may be cyclical stress, fracture, faulty repair, mechanical overload, overheating, and many others. There are variety of statistical distributions which cover time to failure analysis as lognormal, Weibull, exponential, Poisson and few more but these distributions fails to ensure the failures due to fatigue. This failure strengthen the investigation about factors that cause fatigue measurements in statistical processes further intend to know the status of these processes in-control and later capable. This paper exemplifies a procedure to estimate process capability indices through a data set containing fatigue measurements. |
Keywords and phrases: fatigue measurements, statistical process control, process capability indices.
