This is the proceedings of the IUTAM Symposium on Exploiting
Nonlinear Dynamics for Engineering Systems that was held in Novi
Sad, Serbia, from July 15th to 19th, 2018. The appearance of
nonlinear phenomena used to be perceived as dangerous, with a
general tendency to avoid them or control them. This perception has
led to intensive research using various approaches and tailor-made
tools developed over decades. However, the Nonlinear Dynamics of
today is experiencing a profound shift of paradigm since recent
investigations rely on a different strategy which brings good
effects of nonlinear phenomena to the forefront. This strategy has
a positive impact on different fields in science and engineering,
such as vibration isolation, energy harvesting,
micro/nano-electro-mechanical systems, etc. Therefore, the ENOLIDES
Symposium was devoted to demonstrate the benefits and to unlock the
potential of exploiting nonlinear dynamical behaviour in these but
also in other emerging fields of science and engineering. This
proceedings is useful for researchers in the fields of nonlinear
dynamics of mechanical systems and structures, and in Mechanical
and Civil Engineering.
Nonlinear phenomena should play a crucial role in the design and
control of engineering systems and structures as they can
drastically change the prevailing dynamical responses. This book
covers theoretical and applications-based problems of nonlinear
dynamics concerned with both discrete and continuous systems of
interest in civil and mechanical engineering. They include
pendulum-like systems, slender footbridges, shape memory alloys,
sagged elastic cables and non-smooth problems. Pendulums can be
used as a dynamic absorber mounted in high buildings, bridges or
chimneys. Geometrical nonlinearities introduced by pendulum motion
may change the system dynamics, and entail a rapid increase of the
oscillations of both the structure and the pendulum, leading to
full pendulum rotation or chaotic dynamics. To magnetorheological
damping is proposed. Nonlinear mechanics has to be used to explain
undesired response in slender footbridges, such as that occurred in
the famous event of the London Millenium Bridge. The observed
phenomena can be explained by an analytical nonlinear discrete-time
model. Shape memory alloys (SMAs) exhibit very interesting
nonlinear thermo-mechanical properties such as shape memory effect
and superelasticity. SMA elements integrated within composite beams
or plates can be used for active modification of structure
properties e.g. by affecting their natural frequencies. Finite
amplitude, resonant, forced dynamics of sagged, horizontal or
inclined, elastic cables have recently undergone meaningful
research advances concerned with modelling, analysis, response, and
nonlinear/nonregular phenomena. A variety of features of nonlinear
multimodal interaction in different resonance conditions are
comparatively addressed. Non-smooth systems are very common in
engineering practice. Three mechanical engineering problems are
presented: (i) a vibro-impact system in the form of a moling
device, (ii) the influence of the opening and closing of a fatigue
crack on the host system dynamics, and (iii) nonlinear interactions
between a rotor and snubber ring system. This book is aimed at a
wide audience of engineers and researchers working in the field of
nonlinear structural vibrations and dynamics, and undergraduate and
postgraduate students reading mechanical, aerospace and civil
engineering.
This is the first book which exploits concepts and tools of global
nonlinear dynamics for bridging the gap between theoretical and
practical stability of systems/structures, and for possibly
enhancing the engineering design in macro-, micro- and
nano-mechanics. Addressed topics include complementing theoretical
and practical stability to achieve load carrying capacity;
dynamical integrity for analyzing global dynamics, for
interpreting/predicting experimental behavior, for getting hints
towards engineering design; techniques for control of chaos;
response of uncontrolled and controlled system/models in applied
mechanics and structural dynamics by also considerung the effect of
system imperfections; from relatively simple systems to
multidimensional models representative of real world applications;
potential and expected impact of global dynamics for engineering
design.
