From: Overdamping of vibration resonances by liquid crystal elastomers
The full spectrum of plate vibration attenuation (FFT of the raw data on position v. time) of the bare metal plate, and the four 2 mm-damping systems in the identical constrained layer geometry. The low-frequency edge of this spectrum is noise because the FFT of a limited-size sample; the curves are artificially shifted upwards to avoid overlapping their key features.
