Expert system for fatigue crack growth predictions based on fatigue crack closure Important problems in fatigue crack growth of materials Composition of the expert system developed for fatigue crack growth predictions FatiCraGro Expert Part I of the expert system: Material details Part II of the expert system: Fatigue crack growth properties Part III of the expert system: Specimens and their Stress Intensity Factor K Expression Part IV of the expert system: Load histories and Cycle Counting Part V of the expert system: Detailed prediction methods of fatigue crack growth Part VI of the expert system: Reporting of results obtained Configuration of the expert system and Installing and running the expert system. 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.
