This study includes both an experimental and theoretical analysis of the effect of residual stresses on the fatigue life of butt-welded low-alloy steel structures. The purpose is to develop a more complete method to estimate the total fatigue life of a weldment. To theoretically calculate the total fatigue life the process was considered as a combination of crack initiation and crack propagation lives. The initiation portion was based on an extension of the local-strain fatigue life initiation model to accomodate the effect of residual and mean stresses. To determine the local notch-root stress-strain condition more accurately a relationship between the fatigue notch and stress concentration factors was developed. Using elastic superposition and modifying Neuber's equation, which relates nominal stress-strain to local notch-root stress-strain residual stresses at the weld-toe were simulated. This analysis allows a more complete estimation of crack initiation life. For the theoretical analysis of fatigue crack propagation life Forman's equation with an appropriate combination effective stress ratio, axial and bending stresses along with residual stress effects was considered. To incorporate the residual stress distribution at the weld-toe a theoretical expression which correlates closely with experimentally determined distributions was developed. Unlike previous investigations this analysis allows the study of the combined effects of axial loading, bending stresses and residual stresses on the fatigue crack propagation life to be considered. With this theoretical model the total fatigue life can be predicted using basic material properties and the loading history including any surface treatment. To test the suitability of this analysis it was applied to welds with mechanically and thermally induced surface stresses. The residual stresses due to various treatments (annealing, tensile preloading, glass and steel shot peening, single and multiple point hammer peening and stress peening) were used to theoretically predict the total fatigue life. The more complete theoretical analysis of the total fatigue life was compared to the experimental results for all the treated and untreated welded specimens. The results show very good agreement; the variations in applied stress for a given fatigue life were between four to 15% for all the treatments listed above.

This book contains the fully peer-reviewed papers presented at the Third Engineering Foundation Conference on Small Fatigue Cracks, held under the chairmanship of K.S. Ravichandran and Y. Murakami during December 6-11, 1998, at the Turtle Bay Hilton, Oahu, Hawaii. This book presents a state-of-the-art description of the mechanics, mechanisms and applications of small fatigue cracks by most of the world's leading experts in this field. Topics ranging from the mechanisms of crack initiation, small crack behavior in metallic, intermetallic, ceramic and composite materials, experimental measurement, mechanistic and theoretical models, to the role of small cracks in fretting fatigue and the application of small crack results to the aging aircraft and high-cycle fatigue problems, are covered.
