Small Cracks and High-Cycle Fatigue
Aerospace, 1996Abstract The problem of high-cycle fatigue (HCF) failures that has recently plagued the aircraft jet-engine industry is associated with the rapid growth of small defects under the action of high-frequency vibrational or resonant loading; such defects have been associated with regions of microstructural damage attributed to such processes

Critical issues in high cycle fatigue
International Journal of Fatigue, 1999High cycle fatigue (HCF) failures in materials used in rotating components of gas turbine engines have often been found to be attributable to fatigue loading on materials which have sustained damage from other sources. Damage can be present in the form of initial material or manufacturing defects, or can develop during service operation.

Damage Mechanisms in High Cycle Fatigue
1999Abstract : This program was designed to allow interaction between MURI investigators and Southwest Research Institute and to allow SwRI to perform independent research on high cycle fatigue mechanisms. The program goals were met. Two students performed experiments with the SwRI micromechanics facilities. Four manuscripts for publication are included in

High cycle spectrum fatigue of welded components: Dissertation
1995High cycle spectrum fatigue of welded components has been investigated. The experimental program included fatigue tests of longitudinal non-load carrying fillet weld specimens manufactured from carbon and stainless steels, fatigue of large welded box beam components, and static hot spot strain measurements.
