An appearance of a flutter in oscillating structures is an endemicphenomenon. Most common causes are vibrations induced by the moving flow of agas (air, liquid) which is interacting with the structure. Typical examplesinclude: turbulent jets, vibrating bridges [Tacoma bridge], oscillating facialpalate at the onset of apnea. In the case of an aircraft it may compromise itssafety. The intensity of the flutter depends heavily on the speed of the flow(subsonic, transonic or supersonic regimes). Thus, reduction or attenuation offlutter is one of the key problems in aeroelasticity with applications to avariety of fields including aerospace engineering, structural engineering,medicine and life sciences.
