Improvement in the Fatigue Strength of Notched Bars by Compressive Self-stresses

Source

In this investigation the long-life fatigue strength of sharply notched steel bars was improved by as much as 300 percent with the introduction of compressive self-stresses. Compressive self-stresses were produced by an axial tensile preload. Quantitative estimates of this improvement were made as a function of preload using suitable failure criteria and an analytical estimate of the stable self-stress distribution. The importance of the distribution in depth is demonstrated. A criterion for predicting crack propagation is improved and clarified.
