The purpose of this book is to provide students, practicing engineers
and scientists with a treatment of nonlinear phenomena occurring in
physical systems. Although only mechanical models are used, the theory
applies to all physical systems governed by the same equations, so that
the book can be used to study nonlinear phenomena in other branches of
engineering, such as electrical engineering and aerospace engineering,
as well as in physics. The book consists of two volumes. Volume I is
concerned with single- degree-of-freedom systems and it presents the
fundamental concepts of nonlinear analysis. Both analytical methods and
computer simulations are included. The material is presented in such a
manner that the book can be used as a graduate as well as an
undergraduate textbook. Volume II deals with multi-degree-of-freedom
systems. Following an introduc- tion to linear systems, the volume
presents fundamental concepts of geometric theory and stability of
motion of general nonlinear systems, as well as a concise discussion of
basic approximate methods for the response of such systems. The material
represents a generalization of a series of papers on the vibration of
nonlinear multi-degree-of-freedom systems, some of which were published
by me and my associates during the period 1965 - 1983 and some are not
yet published.
