Study on Mechanism and Inversion of Zigzag Dispersion Curves in Rayleigh Wave Exploration

Chinese Journal of Geophysics, 2000
Abstract The propagation mechanism of zigzag dispersion curves in the Rayleigh wave exploration is theoretically analyzed. The propagation characteristics and interrelation of the guided waves are studied. It is suggested that the zigzag structure of Rayleigh wave is the result of the many modes generated by the low‐velocity layers or

Bubbles in the close vicinity of breaking waves: Statistical characteristics of the generation and dispersion mechanism

Journal of Geophysical Research: Oceans, 1988
A direct investigation focussed on the vicinity of the interface of bubble populations generated by different breaking wave fields in a wind‐water simulation facility is presented. Bubble size spectrum over a diameter range 60 μ ≤ d < 3000 μ, obtained from a laser‐based single‐particle technique is given for different depths in the vicinity of the ...

Anisotropic wave dispersion and band‐gaps in mechanical metamaterials via the relaxed micromorphic model

PAMM, 2018
AbstractWe propose a continuum model (the relaxed micromorphic model) to describe band‐gap phenomena in metamaterials.

Statistical nano-chemo-mechanical assessment of shale by wave dispersive spectroscopy and nanoindentation

2011
Shale is a common type of sedimentary rock formed by clay particles and silt inclusions, and, in some cases, organic matter. Typically, shale formations serve as geological caps for hydrocarbon reservoirs. More recently, various shale formations have been identified as prolific sources of oil and natural gas and as host lithologies for the disposal of ...
