Damping Capacity of Turning Tools, Part 2: Mechanism Initiating the Damping Capacity

Journal of Engineering for Industry, 1993
This paper examines the mechanism initiating the damping capacity of a turning tool. The turning tool is considered as a beam on an elastic foundation. Parameters of the model are estimated from the experimental result of the free damped vibration frequency.

DAMPING CAPACITY OF BULK WHEAT

Transactions of the ASAE, 1999
Results of resonant column tests on 23 specimens of bulk wheat, showing effects of strain amplitude, confining stress, wheat type (hard and soft red winter wheat), wheat density, and moisture content on wheat damping capacity are presented, along with models relating damping capacity to shear strain amplitude and to corresponding shear stiffness ...

Damping capacity of layered materials

Journal of Applied Physics, 1994
Extensive measurements of the internal friction in a variety of layered materials such as graphite, metal dichalcogenides (MoS2, TiS2, NbSe2, TaS2, TaSe2, and TaTe2), and montmorillonite clays are reported. The internal friction of these layered materials exhibits features similar to those observed in graphite.

Damping capacity of nanotwinned copper

Acta Materialia, 2008
Abstract Copper with different twin densities was obtained by its deposition from the vapour phase in the form of coatings or separated condensates (foils) on substrates kept at different temperatures. True values of the logarithmic decrement (LD) for copper were calculated from LD amplitude dependences, measured for the coating–substrate system in ...

Biomimetic Gradient Polymers with Enhanced Damping Capacities

Macromolecular Rapid Communications, 2016
Designing gradient structures, mimicking biological materials, such as pummelo peels and tendon, is a promising strategy for developing advanced materials with superior energy damping capacities. Here a facile and effective approach for fabricating polymers with composition gradients at millimeter length scale is presented.

Damping Capacity of Fe-Ga Alloys

Advanced Materials Research, 2011
The damping capacity of Fe-Ga rods and sheets has been studied using a computer-controlled automatic inverted torsion pendulum instruments in a wide temperature range in a series of frequency. The frequency and temperature has different influence on the damping capacity of solidified Fe83Ga17 rods and (Fe83Ga17)97.25Cr2B0.75 sheets.

Damping capacity of Fe-Ru alloys

Scripta Materialia, 2000
In previous studies, some of the authors have reported that an Fe-17%Mn alloy undergoing non-thermoelastic {gamma}(fcc){r_arrow}{epsilon}(hcp) martensitic transformation possesses a high damping capacity, and that the damping capacity is closely related to the amount of {epsilon} martensite. Blackburn et al. investigated the transformation behaviors of
