Entry: S wave
URI: https://registry.epos-eu.org/ncl/FAIR-Incubator/tcs-SEISMO/62
Elastic waves producing shear and no volume change are called S waves (S standing for Latin Secundae or 'secondary'). In a homogeneous, isotropic, linear elastic medium the velocity of S waves is equal to (?/?)-1/2, where ? and ? are the rigidity and density, respectively. For a classical isotropic linear elastic medium (in an isotropic far field), the particle displacement associated with S waves is perpendicular to the direction of wave propagation, so they are sometimes called 'transverse waves'. In an isotropic full space, only S waves generate rotational motions. For isotropic Cosserat continua, the S wave becomes a mixed shear-rotational wave. In anisotropic media, it couples also with P waves
