Numerical-experimental methods for estimating the fatigue resistance characteristics of asymmetrically loaded structural aluminum alloys

摘要

The equation of the limiting-amplitude diagram of the stress cycle of axially loaded structural aluminum alloys is derived on the basis of extensive experimental material. The dependence of the coefficient of the sensitivity to the loading cycleasymmetry on the number of cycles to fracture and the static strength of the alloys is established. Errors inherent in the proposed equations are estimated.
