A method to assess notched fatigue behaviour

A method to estimate the strength reduction factors ( K f ) of notched fatigue specimens is presented. It is shown that the influence of the notch geometry on fatigue life can be assessed by photoelastic analysis. A simple mathematical expression to estimate the value of K f has been put forward.

Zusammenfassung:	A method to estimate the strength reduction factors ( K f ) of notched fatigue specimens is presented. It is shown that the influence of the notch geometry on fatigue life can be assessed by photoelastic analysis. A simple mathematical expression to estimate the value of K f has been put forward. The validity of the expression has been verified experimentally by comparing against fatigue test results.
