The author discusses in detail the fundamentals and recent advances in fatigue analysis with special emphasis on crack mechanics and fatigue design of structural details. This title is intended for engineers, research staff, professors and graduates engaged in fatigue preventing design and survey, fatigue studies of materials and structures, planning repair and maintenance, and strength standard development. This monograph presents the state-of-the-art and recent advances, including those by the author, in fatigue studies. It is designed to be a useful tool in many practical applications. The fatigue damage of structures is discussed mainly as a two-stage process consisting of a crack nucleation phase and a sub-critical crack propagation phase. Crack initiation models are regarded relevant for fatigue design and the crack propagation models are regarded as the means of fatigue reliability assessment of structures. Major factors affecting crack initiation and propagation are examined. The S-N curve and Local Strain formats are used to model the damage process in the initiation period. By defining the initial crack size, provisional though, the necessary link between the stages of the process is provided. The crack growth is specified mostly in terms of linear fracture mechanics, however the unified approaches are suggested based on the application of cyclic plasticity. The emphasis is put on the effects of stress concentration, residual welding stresses, and random loading, as well as on statistical aspects of the damage accumulation and crack growth. Special attention is focused on the methodologies of the fatigue design of structural details, including the procedures approved by the classification societies.
The methodologies and information in the book are addressed to engineers, naval architects, research staff, professors and graduates engaged in fatigue preventing design and survey of marine structure, in fatigue studies of materials and structures, in experimental laboratory research, in planning the repair and maintenance of affected structures, and in rule development including in-service reliability systems, etc. The book is also an effective educational aid in naval architecture, marine, civil and mechanical engineering. The author, a professor at St. Petersburg Marine Technical University and the head of Strength & Reliability Laboratory, Mechanical Engineering Research Institute, Russian Academy of Sciences, is an internationally recognized expert leading for decades in experimental and theoretical research in this field.
