An experimental investigation of flexural-gravity waves was performed in the Hamburg Ship Model Basin HSVA ice tank. Physical characteristics water-ice system were measured several locations tank with a few sensors deployed water and on during tests. The three-dimensional motion optical Qualisys; pressure by mounted wall, in-plane deformations temperatures fiber optic sensors; acoustic emission...

Abstract We show well-posedness for the equations describing a new model of slightly compressible fluids. This was recently rigorously derived in Grandi and Passerini (Geophys Astrophys Fluid Dyn, 2020) from full set balance laws falls category anelastic Navier–Stokes In particular, we prove existence uniqueness global regular solutions two-dimensional case initial data arbitrary “size”, “small...

[1] We measure seismic attenuation beneath North America using waveform cross-correlation and cluster analysis, and obtain images of the laterally varying anelastic structure of the upper mantle. Cluster analysis improves attenuation measurements by systematically comparing only highly similar waveforms, which reduces bias from scattering, directional differences in source functions, and source...

Complex two-component peak of anelastic mechanical losses was observed in multicomponent substitutional austenitic alloys after prior plastic deformation. In AISI 316L, AISI 316LN, AISI 310 and AISI 304 austenitic stainless steels, this peak is situated in the wide range of temperature from 200 to 400K. Characteristics of the observed peak for different thermo-mechanical treatments were studied...

We introduce a low Mach number equation set for the large-scale numerical simulation of carbon-oxygen white dwarfs experiencing a thermonuclear deflagration. Since most of the interesting physics in a Type Ia supernova transpires at Mach numbers from 0.01 to 0.1, such an approach enables both a considerable increase in accuracy and a savings in computer time compared with frequently used compre...

Anelastic tomography provides new insights into the thermal structure of the earth's upper mantle. Lateral variations in Q are largest in the upper 300 km, but remain significant down to at least 500-600 km. They correlate with the distribution of plates in the upper 300 kin, in agreement with cooling plate models and with the distribution of hotspots at greater depths. Two major upwellings are...

There has been increasing appreciation over recent years of the importance of the studies reported by Gorsky in the 1930s concerning the influences of strain gradients on the processes of diffusion in metals (1-3). These strain gradients can, for example, be produced by mechanical bending. As a particular case of strain induced diffusion, evidence has been obtained from anelastic effects-such a...

Ceriuii dioxide doped with y 3 + ions, which is of interest for its ionic conductivity, is here studied by anelastic ~~~ethods. The internal friction peaks observed are analyzed intc peals A , B, C (with Hr = 0.64, 0.71 and 0.78 eV, respectively). Peak A, present at low y3+ concentrations is established to be due to a W pair (V = oxygen-ion vacancy), which is a charged defect conpensated by an ...

Coupled atmosphere-fire modeling is recognized as a relevant approach for the representation of interaction between wildland fire and local meteorology at landscape scales. The atmospheric model component used in coupled system based on several approximations, which are adopted computational efficiency or physical processes representation, including widely anelastic approximation. validity doma...

The effect of hydrogen charging on the lattice dilation in an ASTM A710-HSLA steel specimen was studied using neutron diffraction. First, spatially-resolved strain measurements were made on a pre-cracked steel double cantilever beam specimen under a constant crack opening displacement (COD). Measurements were made at the crack tip region for in-plane and throughthickness lattice strains. Then, ...
