From the reviews:
“This is a book dealing with the practical engineering problem as to how to successfully design riveted fuselage lap-joints, as well as how to perform simple and advanced analyses to substantiate the design. I believe that this book is an essential reference for aircraft designers as well as for fatigue analysts that will need to substantiate the design for adequate fatigue life and for selecting meaningful inspections for cracks.” (Abraham Brot, Israel Society of Aeronautics and Astronautics, October, 2013)“The authors have collected and analysed numerous older and more recent reports, papers, and doctoral theses associated with fatigue of riveted lap joints. … The book with over 300 pages is amply provided with instructive figures. Whenever fatigue of lap joints must be considered for designing a fuselage or analysing fatigue in lap joints of existing aircraft, this book should be consulted. There is no comparable book with such a comprehensive and explanatory description of fatigue of riveted lap joint.” (Jaap Schijve, International Journal of Fatigue, Vol. 51, 2013)
