Anelasticity in thin-shell nanolattices. [PDF]
Proc Natl Acad Sci U S A, 2022 In this work, we investigate the anelastic deformation behavior of periodic three-dimensional (3D) nanolattices with extremely thin shell thicknesses using nanoindentation. The results show that the nanolattice continues to deform with time under a constant load. In the case of 30-nm-thick aluminum oxide nanolattices, the anelastic deformation accounts

Insights on Upper Mantle Melting, Rheology, and Anelastic Behavior From Seismic Shear Wave Tomography [PDF]
Geochemistry, Geophysics, Geosystems, 2018 In seismic tomography we map the wave speed structure inside the Earth, but we ultimately seek to interpret those images in terms of physical parameters.

A New Anelasticity Model for Wave Propagation in Partially Saturated Rocks
Energies, 2021 Elastic wave propagation in partially saturated reservoir rocks induces fluid flow in multi-scale pore spaces, leading to wave anelasticity (velocity dispersion and attenuation).

Small-on-large geometric anelasticity. [PDF]
Proc Math Phys Eng Sci, 2016 In this paper, we are concerned with finding exact solutions for the stress fields of nonlinear solids with non-symmetric distributions of defects (or more generally finite eigenstrains) that are small perturbations of symmetric distributions of defects with known exact solutions. In the language of geometric mechanics, this corresponds to

Revealing anelasticity and structural rearrangements in nanoscale metallic glass films using in situ TEM diffraction [PDF]
Materials Research Letters, 2017 We used a novel diffraction-based method to extract the local, atomic-level elastic strain in nanoscale amorphous TiAl films during in situ transmission electron microscopy deformation, while simultaneously measuring the macroscopic strain.

P-wave anelasticity in hydrate-bearing sediments based on a triple-porosity model
Frontiers in Earth Science, 2023 P-wave anelasticity (attenuation and dispersion) of hydrate-bearing sediments depends on several factors, namely the properties of the mineral components, hydrate content and morphology, and fluid saturation.

Review of progress in seismic attenuation tomography
地球与行星物理论评, 2022 Global and regional seismic attenuation models reveal anelastic heterogeneous structures in the earth, which shed new light on the temperature, melt and volatile fraction of Earth's interior, as well as the geodynamic processes and source focal ...

Relativistic anelasticity [PDF]
Classical and Quantum Gravity, 2006 A formulation of Continuum Mechanics within the context of General Relativity is presented that allows for the incorporation of certain types of anelastic material behaviour, such as viscoelasticity and plasticity. The approach is based on the concept of a four-dimensional body-time complex structured as a principal bundle.

The Anelasticity of the Earth [PDF]
Science, 1964 The attenuation of seismic waves is one manifestation of the earth's anelasticity and is not unrelated to the response of the earth to stresses of longer duration. The well-known difficulties involved in the extraction of meaningful amplitude information from body waves have prevented an accurate determination of attenuation of seismic energy versus ...
