Theoretical Determination of Fatigue Strength at Stress Concentration
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 author's 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.
