From the reviews of the first edition: "This is a very useful book for the analysis of vibro-impact systems. It is written in the great Russian tradition of mechanics entwined with mathematics, but the fundamental introductions of the chapters always lead to explicit calculational schemes. … As a whole this book is a good introduction ... Read moreto a very important part of engineering mathematics." (Ferdinand Verhulst, SIAM Reviews, Vol. 45 (2), 2003) "This book deals with periodic vibrations of strongly nonlinear dynamical systems, with special attention to mechanical systems with impacts, which are investigated for their own relevance and as approximations of other strongly nonlinear systems. … The book is well organized and the arguments are illustrated in a sequential and logical order." (Meccanica, Vol. 39, 2004) "In this book, first published in Russian, analytic approaches are presented for the description of strongly nonlinear mechanical systems with the solution of non-linear second order differential equations arising in leading to time-periodicity of the coefficients in the different equations. … The text is fluent and well illustrated." (European Journal of Mechanical and Environmental Engineering, Vol. 47 (4), 2002/2003) "This book investigates vibrations of nonlinear mechanical systems characterized by the presence of threshold nonlinear positional forces. … In the reviewer opinion, the book presents many original solutions of dynamical problems for strongly nonlinear systems, and thus may be considered as a first systematical description of the theory of vibrations of strongly nonlinear systems with lumped parameters."
