A Survey of Existing Means for Prediction of Fatigue Life.
Abstract
The object of this research is to explore new areas for the prediction of fatigue properties of materials. Both the inherent flaw theory and the finite crack theory were explored in some detail. The major theory considered in the area of inherent flaws was the Bement-Pohler Fatigue Theory. The Structural-Energy Theory along with several crack propagation laws were presented in the chapter dealing with the finite crack theory. Some very promising results were found. With some further testing, these new methods could substantially reduce the cost of establishing a material's fatigue properties. In the conclusions several areas are discussed in which further experimentation is needed. References are made throughout the paper to these areas and their present inadequacies.
