Low frequency damping of metal panels in ambient Air [PDF]

, 2008
Mathematical models of structural dynamics are widely used and applied in many branches of science and engineering and it has been argued that many of the shortfalls with these models are due to the fact that the physics of joint dynamics are not ...
