Abstract:
The mechanism of stress and strain concentration at fatigue loading is governed by two fundamental effects. Within the yield range of ductile materials the macro-support effect is dominating which in this paper is represented by the results of a non-linear theory derived by the author. Within the high-cycle fatigue range the micro-support effect is governing which can be described by the authors theory of mean stress value, originally derived in connection with the calculation of sharply curved notches. In this theory a material constant of length dimension is introduced. Taking into account these two effects an approximate precalculation of the fatigue strength of notched construction parts is possible. Author
