A STUDY OF PRE-CRACK FATIGUE. PART I

The report is an examination of current technological posture in materials fatigue, especially that area of fatigue before the formation of a finite or 'technical' crack. A computerized search of the literature was performed by the Defense Documentation Center leading to the establishment of a bibliography which was intensively examined. The various concepts and rules of fatigue damage were critically examined as were their effects on fatigue analysis. The fatigue implications of Non-Destructive Evaluation (NDE) were also reviewed with the objective of recommending new approaches. Throughout all, a number of specific recommendations for future activity were made and discussed. These are summarized at the conclusion of this report. (Author)
