Existence of one-component Rayleigh waves, Stoneley waves, Love waves, slip waves and one-component waves in a plate or layered plate

Love waves in a piezoelectric layered structure

Consider a layer made of a m3m insulator crystal, with faces cut parallel to a symmetry plane. Then bond it onto a semi-infinite mm2 piezoelectric substrate. For a Xor Y -cut of the substrate, a Love wave can propagate in the resulting structure and the corresponding dispersion equation is derived analytically. It turns out that a fully explicit treatment can also be conducted in the case of a ...

Rayleigh Waves

The table of source phase differences between Rayle igh and Love waves which was described in Pa r t I and used in Pa r t 2 is presented in a concise form for the case of a surface focus.

Lamb Waves in a Poroelastic Plate

Currently, bone mineral density (BMD) is the gold standard for in vivo assessment of frac23 ture risk of bones and is measured using X-ray absorptiometric techniques.1 However, only 24 70–80% of the variance of bone strength is accounted for by bone density. As the brittle25 ness of bone depends on more factors than bone density, biologists believe that quantitative 26 ultrasound techniques (QU...

Thermoelastic waves in an anisotropic infinite plate

An analysis of the propogation of thermoelastic waves in a homogeneous, anisotropic, thermally conducting plate has been presented in the context of the generalized Lord-Shulman theory of thermoelasticity. Three different methods are used in this analysis: two of them are exact and the third is a semianalytic finite element method (SAFE). In our exact analysis, two different approaches are used...
