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 ...

Journal of Alloys and Compounds, 1994
Abstract An approach to higher damping by positively utilizing computer-aided control techniques has been investigated by comparing the relative magnitudes of active (computer-controlled) damping and material damping. The active damping effect increases the damping capacity of a brass beam vibration system from δif=0.012 (logarithmic decrement value ...

On the damping capacity of cast irons
The Physics of Metals and Metallography, 2012The treatment of experimental data on the amplitude-dependent internal friction (ADIF) in terms of various theoretical models has revealed a staged character and the main mechanisms of the processes of energy dissipation in graphite with increasing amplitude of vibrations upon cyclic loading.

The damping capacity of VNS-5 steel
Strength of Materials, 19751. As the amount of retained austenite increases (in the limits examined), the damping capacity of the steel increases at all amplitudes of vibration. 2. The increase in the density of defects in the structures facilitates a dissipation of energy only at small amplitudes of unit strain. 3.

Improving the vibration damping capacity of cement
Journal of Materials Science, 1998Cement pastes containing latex (20–30% by weight of cement), methylcellulose (0.4–0.8% by weight of cement) and silica fume (15% by weight of cement, either as received or acid treated) were compared in terms of the dynamic flexural mechanical properties, as expressed by the loss tangent (damping capacity), storage modulus and loss modulus at 0.2–2 Hz (
