E.O. Paton Electric Welding Institute of the NASU 11 Kazymyr Malevych Str., 03150, Kyiv, Ukraine.Abstract
The paper deals with an engineering method of calculating estimation of the influence of cycle asymmetry on fatigue resistance of steel welded joints at different values of base in the high-cycle region of fatigue life. An informative diagram of limiting ranges of stresses based on asymmetry parameters and number of cycles, as well as analytical expressions for its description are suggested
Keywords: welded joints, fatigue resistance, cycle asymmetry, diagram, calculations
