Mini-symposium description 

Traditionally, structural mechanics and fluid-structure interactions tend to avoid harmful instabilities such as buckling and flutter. New engineering applications ranging from dynamics of subcellular structures to green energetics, in contrast, tend to exploit such instabilities, e.g. for energy harvesting or for biomimetic design of microrobots that reproduce natural propulsion mechanism of organelles. The new applications, where such instabilities are desirable, dramatically influence the established approaches to stability analysis of structures, reconsidering the role of elasticity, dissipation, kinematic constraints both in linear and nonlinear settings, and actively absorbing new ideas from physics and modern applied mathematics.

 

In this mini-symposium we welcome researchers from all areas of solid and structural mechanics for discussing nonconservative stability problems in both the classical and in the cutting edge applications. Theoretical, computational and experimental studies are invited of such engineering situations as coupled mode flutter of wings, flags and pipes; electromechanically coupled systems; conventional and soft robotics; wave energy converters; friction-induced vibrations; stability of slender structures under conservative and non-conservative stationary and time-dependent loads; rotor dynamics; stability of moving continua and wave propagation in infinite dimensional structures; radiation-induced instabilities; biomechanics. 

The goal of this mini-symposium is to bring together theorists, experimentalists and practitioners who are interested in exchanging new challenging nonconservative stability problems in structural mechanics and fluid-structure interactions and novel methods of stability analysis. We believe that such cross-fertilization will both serve for advancement and update of the stability theory and result in new collaborations for investigating new engineering applications.
