Strength calculation of sharp notched components

In this report the strength calculation of sharp notched components under static and cyclic loading is investigated and compared to the FKM code "Analytical strength assessment for machine components". The calculation of the strength of sharp notched components according to the guideline does not lead to satisfying solutions. Therefore different concepts of strength calculation with consideration of scale and notch effects are examined e.g. the gradient concept of Siebel/Stieler. This concept is implemented in the FKM code for the calculation of the notch sensitivity factor. In order to evaluate the numerical results. experimental tests with various sharp notched specimens under static and cyclic loading were carried out. Based on these experimental results the FKM code is extended to sharp notched components.
