Abstract Reflection and critically refracted seismic methods use traveltime measurements of body waves propagating between a source series receivers on the ground surface to calculate subsurface velocities. Body wave energy is or reflected at boundaries where there change in impedance, defined as product material density velocity. This article provides practical guidance horizontally shear (SH-...

Cyclic-tension fatigue of aluminum alloy, Al-4Cu-1Mg, was determined by an analysis of diffracted SH and SV waves, passing through the surface and reflecting the bottom of the specimen, respectively. The internal friction of SV waves begins to increase from fatigue damage ratio(=N/Nf) of 0.5. This suggests increase of movable dislocation. From the analysis of SH waves, the logarithmic damping r...

We consider a general solution of the electromagnetic wave scattering problem for arbitrarily shaped homogeneous particles, whose surface can be expressed by a function of angular coordinates, using a Laplace series expansion. This can include regularly shaped particles (e.g., ellipsoids and cubes) as well as irregularly shaped particles like Gaussian spheres. For calculations of scattering pro...

This paper investigates the feasibility of site characterization via spectral analysis of horizontally-polarized shear (SH) waves as a means to lter the eeects of pore water for saturated soil conditions. Using a multi-layered wave propagation model to simulate the proposed testing connguration revolving around a torsionally vibrating loading plate, it is shown that the use of generalized Love ...

SUMMARY Long-period (T > 10 s) shear wave reflections between the surface and reflecting boundaries below seismic stations are useful for studying phase transitions in mantle transition zone (MTZ) but shear-velocity heterogeneity finite-frequency effects complicate interpretation of waveform stacks. We follow up on a recent study by Shearer & Buehler (hereafter SB19) top-side reflect...

The separation of wave-modes for isotropic elastic wavefields is typically done using Helmholtz decomposition. However, Helmholtz decomposition using conventional divergence and curl operators in anisotropic media only partially separates the elastic wave-modes. The separation of anisotropic wavefields requires operators which depend on local material parameters. Wavefield separation operators ...
