Damping is the conversion of mechanical energy of a structure into thermal energy. The amount of energy dissipated is a measure of the structure’s damping level. So i want to know how damping will vary with crystal structures like bcc,fcc,hcp..
The dissipation of mechanical energy in bcc, hcp, and fcc crystalline structures (damping / internal friction / logarithmic decrement and mechanical loss angle / phase lag, etc.) is a vast subject. A number of similar damping mechanisms exist in bcc, fcc, and hcp structures. Nonetheless, damping phenomena in these structures must be considered separately for different metals, alloys, samples, and experimental conditions.
An exhaustive list of books and Conference Proceedings devoted to this area is published in Mater. Sci. Eng. A vol. 521-522, pp. 405-415 (2009); see attached paper. For a brief introduction see the classic book of Nowick and Berry. You can find several excellent review papers on damping in crystalline structures in Conference Proceedings from international conferences on internal friction and mechanical spectroscopy. Relevant references are also provided in the recommended paper.
