Abstract

The article deals with the problem associated with the acelerated determination of the endurance limit of steel objects. It is proposed to use the sloped section of the fatigue curve in logarithmic coordinates to solve this problem, constructed according to the classical technique according to the power equation. In this case, the endurance limit is proposed to be found by the parameters of the fatigue curve equation, expressed by the Weibull equation, obtained by recalculation. Experimental verification of the proposed approach on smooth and notched specimens made of steel 45 showed that the errors of the proposed method are within acceptable limits
