This book suggests a new common approach to the study of resonance
energy transport based on the recently developed concept of
Limiting Phase Trajectories (LPTs), presenting applications of the
approach to significant nonlinear problems from different fields of
physics and mechanics. In order to highlight the novelty and
perspectives of the developed approach, it places the LPT concept
in the context of dynamical phenomena related to the energy
transfer problems and applies the theory to numerous problems of
practical importance. This approach leads to the conclusion that
strongly nonstationary resonance processes in nonlinear oscillator
arrays and nanostructures are characterized either by maximum
possible energy exchange between the clusters of oscillators
(coherence domains) or by maximum energy transfer from an external
source of energy to the chain. The trajectories corresponding to
these processes are referred to as LPTs. The development and the
use of the LPTs concept a re motivated by the fact that
non-stationary processes in a broad variety of finite-dimensional
physical models are beyond the well-known paradigm of nonlinear
normal modes (NNMs), which is fully justified either for stationary
processes or for nonstationary non-resonance processes described
exactly or approximately by the combinations of the non-resonant
normal modes. Thus, the role of LPTs in understanding and analyzing
of intense resonance energy transfer is similar to the role of NNMs
for the stationary processes. The book is a valuable resource for
engineers needing to deal effectively with the problems arising in
the fields of mechanical and physical applications, when the
natural physical model is quite complicated. At the same time, the
mathematical analysis means that it is of interest to researchers
working on the theory and numerical investigation of nonlinear
oscillations.
