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 ...

On the interaction of exponential non-viscous damping with symmetric nonlinearities [PDF]
, 2008 This paper studies the interaction between non-viscous damping and nonlinearities for nonlinear oscillators with reflection symmetry. The non-viscous damping function is an exponential damping model which adds a decaying memory property to the damping ...

Chatter Stability in Turning and Milling with in Process Identified Process Damping
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2010 Process damping in metal cutting is caused by the contact between the flank face of the cutting tool and the wavy surface finish, which is known to damp chatter vibrations.

Damping Seiches and Estimate of Damping, Linear Frictional Coefficients
Japanese Journal of Limnology (Rikusuigaku Zasshi), 1979 The frictional effect on the period of surface seiches in Lake Biwa has been discussed by TAKAHASHI and NAMEKAWA (1931). They concluded that the seiches of the longest period of 4 hours in Lake Biwa may be considered as a bay oscillation in the southern basin, and the difference of the period between the observed and theoretical one is due to an ...

A study of joint damping in metal plates [PDF]
, 2009 For satellite applications the determination of the correct dynamic behaviour and in particular the structural damping is important to assess the vibration environment for the spacecraft subsystems and ultimately their capability to withstand the launch ...
