Abstract:

This study addressed itself to the development of a practical engineering tool based on the Stress-Strength Interference Theory to be used for designing and quantitatively predicting the reliability of mechanical parts subjected to mechanical loading. Fatigue data were gathered for various ferrous materials, heat treatments, surface conditions, etc. and were converted to strength data to obtain the scatter of strength at a given life. The Weibull distribution best fit the data and was found to be the most effective means of representing the strength distribution in the interference Theory. For each material parameter studied, Weibull parameters were calculated and presented in tabular and graphic form.
