Particle damping is a type of impact damping that is designed to mitigate the response of lightly damped structures under dynamic loading. It consists of granular materials constrained to move between two ends of a cavity in a structure. When attached to a vibrating structure, the collisions of individual particles with cavity boundaries result in a reduction in the vibration amplitude of the s...
In this paper, the vibrations of thin plate in modified couple stress thermoelastic medium by using Kirchhoff- Love plate theory has been investigated. The governing equations of motion and heat conduction equation for Lord Shulman (L-S) [1] theory are written with the help of Kirchhoff- Love plate theory. The thermoelastic damping of micro-beam resonators is analyzed by using the normal mode a...
In dynamic plowing lithography, the sample surface is indented using a vibrating tip in tapping mode atomic force microscopy. During writing, the gap between the cantilever and the sample surface is very small, usually on the order of micrometers. High vibration frequency and small distance induce squeeze film air damping from the air in the gap. This damping can cause variations in the cantile...
Damping measurements were carried out on two-phase (y-matrix, y'-precipitates) nickel-base alloys containing different volume fractions of y' in order to achieve a better understanding of the strong elastic modus decrease between 1000°C and 1 100°C. For the investigation of the damping a free-free beam flexural vibration technique was applied. Nickel-base alloys with a high volume fraction of y...
