Abstract

The standard diagram is described, giving the relationship between R and S for constant value of N. The line of infinite endurance is obtained, and the relationship of N and S is shown. The effects of stress concentration and of shape are studied and tabulated. The variation of KF with S1 is plotted, and the relationship between KF, KT and S1 is examined. Comments are made on the variation of KF with material, on high compressive stress, on surface finish effect and on the relationship between the grades of light alloy. The effects of bending, riveting and bolting are shown. General discussion summarizes the results and makes suggestions for future research and testing for fatigue. An appendix contains notes on practical use of the results in design, and some examples of fatigue stress analysis and its application to pressurized cabins.
