"This book provides an important contribution to the challenging world of nonlinear structural dynamics and mechanical vibration. One of the most interesting features of the book is the perfect balance the authors have provided, between computational and experimental methods, and between theory and practical applications. I strongly recommend this book to researchers (in engineering and sciences) and practicing engineers (in aerospace, civil, and mechanical industries) who are actively investigating the role of nonlinearities in structural and mechanical systems. It could be used as a supplementary or reference text for graduate and undergraduate students in this field."-R. Singh, Ohio State University
