Partial coverage of rectangular plates by unconstrained layer damping treatments
TLDR
In this paper, the effects of partial application on the modal frequencies, loss factors and mode shapes are discussed, and specific recommendations are made for the near-optimum distribution of the damping material on the panel surface which is effective for many modes of panel response.About:

On the formation of complex modes in non-proportionally damped systems
Can Nerse,Semyung Wang +1 more
TL;DR: In this article, the difference between a complex mode and a real normal mode is represented by the summation of patterns that propagate from the boundaries, and the governing equation for this phenomenon is expressed by Snell's law.

The optimum use of unconstrained layer damping treatments.
D J Mead,T G Pearce +1 more
TL;DR: In this paper, the effect of concentrating the treatment in the regions of highest bending moment in order to use all the material more effectively was investigated, and three methods of analysis were presented, two of them being approximate but relatively rapid in use.
