A Note on Fatigue Scatter and Life Predictions
One of the major problems in predicting fatigue life for service components from laboratory data is that the scatter of laboratory data often differs from that of actual service components. In this note a method to estimate fatigue lives from crack propagation models is presented. It will be shown that the result is a scatter and life prediction which well represents those desired for typical manufactured parts.
