For the many different deterministic non-linear dynamic systems
(physical, mechanical, technical, chemical, ecological, economic, and
civil and structural engineering), the discovery of irregular vibrations
in addition to periodic and almost periodic vibrations is one of the
most significant achievements of modern science. An in-depth study of
the theory and application of non-linear science will certainly change
one's perception of numerous non-linear phenomena and laws considerably,
together with its great effects on many areas of application. As the
important subject matter of non-linear science, bifurcation theory,
singularity theory and chaos theory have developed rapidly in the past
two or three decades. They are now advancing vigorously in their
applications to mathematics, physics, mechanics and many technical areas
worldwide, and they will be the main subjects of our concern. This book
is concerned with applications of the methods of dynamic systems and
subharmonic bifurcation theory in the study of non-linear dynamics in
engineering. It has grown out of the class notes for graduate courses on
bifurcation theory, chaos and application theory of non-linear dynamic
systems, supplemented with our latest results of scientific research and
materials from literature in this field. The bifurcation and chaotic
vibration of deterministic non-linear dynamic systems are studied from
the viewpoint of non-linear vibration.
