Damping of kink waves by mode coupling : I. Analytical treatment [PDF]
, 2013 Aims. To investigate the spatial damping of propagating kink waves in an inhomogeneous plasma. In the limit of a thin tube surrounded by a thin transition layer, an analytical formulation for kink waves driven in from the bottom boundary of the corona is

Effect of the frequency spacing on modal damping estimation of a double-layer grid [PDF]
مهندسی عمران شریف, 2021 Although natural frequencies and mode shapes can be accurately measured by dynamic tests, error bounds in values of damping estimation can be large. Since damping strongly influences the design and control of structures, efforts are made to find the ...

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 ...

Vibration Analysis of Cylindrical Sandwich Aluminum Shell with Viscoelastic Damping Treatment
Advances in Materials Science and Engineering, 2013 This paper has applied the constrained viscoelastic layer damping treatments to a cylindrical aluminum shell using layerwise displacement theory. The transverse shear, the normal strains, and the curved geometry are exactly taken into account in the ...
