Nonlinear Sound Propagation in Fibrous Sound-Absorbing Materials
Friday, November 3, 2000 4:00 p.m. Professor C. L. Morfey Institute of Sound & Vibration Research University of Southampton Southampton, UK http://www.soton.ac.uk Transverse oscillations of a cylinder in a viscous fluid generate a force on the fluid that becomes nonlinear at large oscillation amplitudes. When the cylinder motion is sinusoidal, nonlinearity produces odd-order harmonic distortion…
