This book demonstrates fatigue crack growth under random loading graphically. This state-of-the-art monograph introduces an expert system for crack growth predictions, particularly based on crack closure. The system is developed after years of research by the authors by using the Math-type software consisting of 5 parts. This system is unique as it is fundamentally different from previous systems as it focuses on fatigue crack growth predictions based on fatigue crack closure. This book can be a useful guide for practicing engineers, researchers, and students in the fields of mechanical, aerospace, or civil engineering.

Author Biography:Jiho Song is Professor Emeritus of Mechanical Engineering at Korea Advanced Institute of Science and Technology (KAIST), Daejeon, Korea. He received his B.S. (1969), M.S. (1971) and Dr. Engineering (1974) in Mechanical Engineering at Osaka University, Osaka, Japan, under the guidance of Professor Makoto Kikukawa. In 1975, he was Wissenschaftlicher Mitarbeiter in Lehrstuhl Mechanik A at Technische Universit�t M�nchen, Munich, Germany, with the help of Professor Klaus Heckel. In 1977 He joined Hanyang University, Seoul, Korea and then moved to Osaka University, Japan, in 1982 as a Research Associate with the support of Professor Masahiro Jono. He returned to Korea in 1985 as a Professor at KAIST, becoming Professor Emeritus in 2011. He taught courses in fatigue, strength design, reliability engineering, and design engineering. He received four times departmental outstanding teaching awards. His principal field of research is fatigue and fatigue-related database and expert system. He published several books: Fatigue Cracks-Crack Closure and Growth Rate Prediction, (in Japanese) in 2005 with Professor Masahiro Jono, (in Korean) in 2006. Introduction to Reliability Engineering, (in Korean) in 2007. Dictionary of Fatigue Fracture and Fatigue Strength of Materials (FatiguePedia of Materials), (in Korean) in 2011. Fundamentals of Fatigue Analysis, (in Korean) in 2016.Book Description:Fatigue of materials is very important in designing mechanical structures and components. Recently, fatigue databases, databanks and some computer software have been developed for fatigue analysis or fatigue life predictions, and some of them have been commercially available. Those fatigue databases and fatigue analysis software tools are clearly very helpful for the design and analysis engineers to select materials, analyze fatigue performance or estimate fatigue life of structures and components. In order to utilize those databases and software tools successfully in practice, engineers as users are implicitly required to have, more or less, wide and deep, and sometimes even advanced knowledge of fatigue; in other words, this book conveys considerable expertise in fatigue. However, most of the design and analysis engineers do not always have sufficient knowledge in fatigue and therefore, it is not yet easy for them to conduct fatigue design and analysis successfully, although there are many databases and software tools available.An expert system is a very useful, convenient and powerful tool for ordinary engineers to treat complicated engineering problems such as fatigue design and analysis, which require considerable expertise. Although the importance of fatigue expert systems has long been recognized, there is hardly any practically available fatigue expert system to date.Over many years, the authors have been developing some expert systems for fatigue assessment, particularly for the estimation of fatigue properties and for fatigue crack initiation life prediction under variable loading. Recently, in response to a scientific research result, the authors have developed a practically applicable version. They think that the expert system developed is probably the first and only fatigue expert system in the world.This book introduces in detail the expert systems developed and provides the expert system software, most probably in CD. Although it is not developed for commercial purposes, the system software is very easy to use.This book and the fatigue expert system software may be useful for nearly all engineers, researchers and technologists from the academic, industrial and government sectors who engage in engineering design and the maintenance of structures. This book is also designed for advanced undergraduate and beginning graduate-level engineering students in universities, particularly in the department of mechanical engineering, aerospace engineering, civil engineering and metallurgy.Target Audience:Nearly all engineers, researchers and technologists from the academic, industrial and government sectors who engage in engineering design and maintenance of structures.Advanced undergraduate and beginning graduate-level engineering students in universities, particularly in the department of mechanical engineering, aerospace engineering, civil engineering, and metallurgy.

Fatigue failure is a multi-stage process. It begins with the initiation of cracks, and with continued cyclic loading the cracks propagate, finally leading to the rupture of a component or specimen. The demarcation between the above stages is not well-defined. Depending upon the scale of interest, the variation may span three orders of magnitude. For example, to a material scientist an initiated crack may be of the order of a micron, whereas for an engineer it can be of the order of a millimetre. It is not surprising therefore to see that investigation of the fatigue process has followed different paths depending upon the scale of phenomenon under investigation. Interest in the study of fatigue failure increased with the advent of industrial ization. Because of the urgent need to design against fatigue failure, early investiga tors focused on prototype testing and proposed failure criteria similar to design formulae. Thus, a methodology developed whereby the fatigue theories were proposed based on experimental observations, albeit at times with limited scope. This type of phenomenological approach progressed rapidly during the past four decades as closed-loop testing machines became available.

An extensive experimental database has been assembled from very detailed teardown examinations of fatigue cracks found in rivet holes of fuselage structural components. Based on this experimental database, a comprehensive analysis methodology was developed to predict the onset of widespread fatigue damage in lap joints of fuselage structure. Several computer codes were developed with specialized capabilities to conduct the various analyses that make up the comprehensive methodology. Over the past several years, the authors have interrogated various aspects of the analysis methods to determine the degree of computational rigor required to produce numerical predictions with acceptable engineering accuracy. This study led to the formulation of a practical engineering approach to predicting fatigue crack growth in riveted lap joints. This paper describes the practical engineering approach and compares predictions with the results from several experimental studies.
