Anelasticity and viscosity of partially molten rock analogue: Toward seismic detection of small quantities of melt [PDF]

open access: yesGeophysical Research Letters, 2011
Anelasticity and diffusion creep viscosity of partially molten rock analogue were measured experimentally at various melt fractions (0.0025–0.04). The presence of even a small quantity of melt phase causes a significant increase in attenuation and ...

Anelasticity of Metals

The Journal of the Acoustical Society of America, 1944
The term anelasticity is used to denote that property of metals in virtue of which strain is not a unique function of stress even at such low stress levels that no permanent set is observed. A review is given of the formal relations between the various anelastic effects, including those which may be measured by acoustical methods.

The Anelasticity of the Mantle

Tectonophysics, 1972
Abstract Data on attenuation of body waves, surface waves and free oscillations are summarized. Virtually all of the seismic attenuation in the mantle occurs in the low-Q zone that corresponds to the low-velocity zone for seismic waves. Regardless of the data source, all experiments show an order of magnitude increase in Q in the region between 400 ...

Anelasticity of Zinc

Journal of Applied Physics, 1952
Anelastic properties of zinc single crystal of high purity (99.996 percent) have been studied, using bars vibrating transversely at audio frequencies in free-free modes. Internal friction, effective elasticity, and shape of resonance curve were determined against the strain amplitude.

Anelastic relaxation in amorphous Pd39.5Ni39.5P21

Materials Science and Engineering, 1988
In order to study the structural relaxation in an amorphous Pd39.5Ni39.5P21 specimen we measured the isothermal change in the internal friction of the asquenched material with an inverted Kê-type torsion pendulum. This change reflects a reduction in the amount of free volume which is quenched-in during manufacturing.

Anelasticity of polycrystalline indium

Materials Science and Engineering: A, 2009
Abstract Mechanisms of anelasticity of polycrystalline indium have been studied over wide ranges of temperature (7–320 K) and strain amplitude (2 × 10 −7 –3.5 × 10 −4 ). Measurements of the internal friction and Young's modulus have been performed by means of the piezoelectric resonant composite oscillator technique using longitudinal oscillations at

Anelasticity in the earth

2013
Published by the American Geophysical Union as part of the Geodynamics Series, Volume 4. The fact that the materials in the solid parts of the Earth depart from perfectly elastic behaviour is now central to fundamental geophysical studies. Slow deformation (creep) by the processes of mantle convection has been widely recognised for about 25 years; it ...
