"The book presents and excellent survey on advanced methods required for the understanding of the complexity of impacts in mechanical systems and presents analytical and numerical methods verified by experimental results for the efficient solution of engineering problems. The book is recommended to graduate and postgraduate students, researchers in mechanical engineering, and scientists who are interested in established methods and new ideas for non-smooth dynamical systems."
