Lamb waves propagate in solid plates or spheres. [1] They are elastic waves whose particle motion lies in the plane that contains the direction of wave propagation and the direction perpendicular to the plate. In 1917, the English mathematician Horace Lamb published his classic analysis and description of acoustic waves of this type. Their ...
Rayleigh waves are distinct from other types of surface or guided acoustic waves such as Love waves or Lamb waves, both being types of guided waves supported by a layer, or longitudinal and shear waves, that travel in the bulk. Rayleigh waves have a speed slightly less than shear waves by a factor dependent on the elastic constants of the ...
EMATs are suitable to generate all kinds of waves in metallic and/or magnetostrictive materials. Depending on the design and orientation of coils and magnets, shear horizontal (SH) bulk wave mode (norm-beam or angle-beam), surface wave, plate waves such as SH and Lamb waves, and all sorts of other bulk and guided-wave modes can be excited.
It depicts an anguished mother sheep standing over the dead body of her lamb, surrounded by a murder of crows. Perhaps Schenck's most famous painting, it is held by National Gallery of Victoria, in Melbourne, Australia since 1880. The painting was an early acquisition by the gallery, just a few years after it was founded, and has been voted the ...
Lamb tattoos are known for their representation of innocence and vulnerability. This imagery often draws parallels to the Christian faith, where the lamb is a sacred symbol of Christ's sacrifice ...
