Oleg Kirillov's picture

Davide Bigoni and Oleg Kirillov co-ordinate the CISM-AIMETA Advanced School on
DYNAMIC STABILITY AND BIFURCATION IN NONCONSERVATIVE MECHANICS
The course will be held at CISM in Udine on April 10-14 2017

Invited Lecturers

Davide Bigoni - Università di Trento, Italy

6 lectures on: The experimental realization of follower forces and the
evidence of flutter and divergence instability. How to experimentally
attack the problem of the Ziegler paradox. Flutter and friction. Flutter
in continuous media: the case of granular materials.

Olivier Doaré - ENSTA ParisTech, France

6 lectures on: Coupled mode flutter of wings, flags and pipes.
Local and global instabilities of slender structures in axial flow.
Damping induced destabilization and negative energy waves in
slender structures coupled to a flow. The piezoelectric flag: coupling
between mechanical and electrical waves, electrical dissipation- and
resonance-induced instabilities.

Oleg Kirillov - Russian Academy of Sciences, Steklov Mathematical
Institute, Moscow, Russia

6 lectures on: Reversible- and Hamiltonian-Hopf bifurcation. Krein
signature and modes and waves of positive and negative energy.
Dissipation-induced instabilities and destabilization paradox.
Influence of structure of forces on stability. Stability optimization and
poles assignment. Overdamped systems and systems with indefinite
damping.

Andrei Metrikine - Delft University of Technology, The Netherlands

6 lectures on: Should high-speed trains move faster than the waves
in the ground? Wave dynamics of infinitely long structures under
moving loads. Anomalous Doppler waves and instability of a vehicle
on an infinitely long structure.

Oliver O’Reilly - University of California, Berkeley, USA

6 lectures on: Modeling nonconservative problems in the dynamics
of rods, strings and chains. Applications ranging from classical problems
in the dynamics of chains to soft-robot locomotion. Conservative
and nonconservative forces and moments in rigid body dynamics.
Applications ranging from brake squeal, locomotion, wave energy
converters, and toys such as the rattleback and dynabee.

Andy Ruina - Cornell University, Ithaca, USA

6 lectures on: Some things in non-holonomic dynamics. Introduction
to non-holonomic dynamics; Degrees of freedom and ‘integrability
of constraints’. Relation to the ‘non-holonomic’ angular momentum
constraint. Falling cat and related experiments. Simple examples of
non-holonomic systems. Sleigh, skateboard, bicycle, ball, disk. How
symmetry can prevent stability. Wings and sails as approximate nonholonomic
constraints; Non-holonomic sailing vs lift and drag sailing;
Non-holonomic airplane.
