Plucking a liquid chord: mechanical response of a liquid crystal filament
University of Magdeburg, Inst. of Experimental Physics
This paper describes an investigation of mechanical properties of freely suspended
liquid filaments. These unique fluid microstructures may be formed by layered liquid crystalline mesophases. The filaments are electrically deflected and stimulated to
mechanical oscillations. Resonance frequencies and damping rates are recorded. We
introduce a model for a basic description of the dynamics, which is used to evaluate
and to discuss the forces involved. The dependence of the oscillation parameters upon
geometrical parameters and temperature is analyzed.
