Preface

Computational and Numerical Simulations is an edited book
including 20 chapters.
Book handles the recent research devoted to numerical simulations
of physical and engineering systems.
It presents both new theories and their applications,
showing bridge between theoretical investigations and possibility
to apply them by engineers of different branches of science.
Numerical simulations play a key role in both theoretical and
application oriented research.

1. Introduction
We study regular and chaotic vibrations of continuous mechanical systems using the following
structural members: plates, flexible shells and cylindrical panels. They are often used in various
measurement devices, and numerous ship and planes constructions. Owing to a high devel‐
opment of technology and due to industrial requirements, in many cases the mentioned
structural members are subjected to action of high intensity loads being spatially and time
dependent. The structural member exhibit either regular or chaotic dynamics, and hence an
important question arises: How to predict safe and dangerous regimes of behavior of the
studied mechanical objects?
In order to solve the mentioned problems, the investigations are carried out using the ach‐
ievements of the qualitative analysis of differential equations and non-linear dynamics.
Namely, we analyze time histories (signals), phase and modal portraits, Poincaré sections,
autocorrelation functions, Lyapunov exponents, Fourier and wavelet spectra. Charts of
vibration regimes versus the load excitation amplitude and frequency are constructed, which
allow to control the vibration character of plates and shells.
Usually the data provided by numerical experiments are presented in time domain. In other
words, we take time as an independent co-ordinate, and amplitude as a dependent co-ordinate,
and the studied signal as analyzed through its amplitude-time representation. However, in
order to understand deeply non-linear continuous systems subjected to various types of load
actions and in order to fully understand the occurring dynamics, we have to apply the
