The present book, Chaos and Fractals in Engineering, is written for all engineers and experts or graduate students or beginners working in the application fields, and for experimental scientists in general. This book is not presented as a pure, theoretical treatise but shows necessarily mathematics at workshop, so to speak, through important applications originating in a deep pure mathematical theory. Widely spread subjects, which the author has encountered hitherto, are briefly addressed in this book, since Chaos and Fractal Engineering is a new frontier of the current research fields nowadays.
