Damping capacity of carbon foam
Materials Science and Engineering: A, 2004Abstract An experimental measurement of dynamic elastic constants and damping capacity expressed by a loss factor in carbon foams is presented. Sample has been placed in free vibration mount in vacuum. Electromagnetic excitation and optical detection of free vibrations have been used.

Damping capacity of layered materials
Journal of Applied Physics, 1994Extensive 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, 2008Abstract 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 ...

Damping Capacity of Fe-Ga Alloys
Advanced Materials Research, 2011The 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, 2000In 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

Microyielding and damping capacity in magnesium
Scripta Materialia, 2014The damping capacity and mechanical response under uniaxial tension and compression were examined for specimens of extruded magnesium inclined by 0°, 15° and 30° relative to the extrusion direction. It was found that both the microyielding under uniaxial deformation and the occurrence of strain-dependent damping capacity pertain to the same physical ...
