Název v původním jazyce
Componental specification of plane waves in isotropic and anisotropic viscoelastic media
Popis výsledku v původním jazyce
Time-harmonic, homogeneous and inhomogeneous plane waves propagating in isotropic and anisotropic viscoelastic media are investigated. The componental specification of the slowness vector p is used, in which the slowness vector p is computed from its known projection p? to an arbitrarily chosen plane ?. The vectors p and p? are, in general, complex-valued. The most important step in the procedure consists in the determination of the component ? of the slowness vector p to the normal n? to ?. For generalanisotropic viscoelastic media, the component ? is a root of an algebraic equation of the sixth degree, with complex-valued coefficients. For isotropic viscoelastic media, the algebraic equation of the sixth degree factorizes to simple quadratic equations. For SH plane waves propagating in the plane of symmetry of a monoclinic (orthorhombic, hexagonal) viscoelastic medium it also factorizes providing a quadratic equation for SH waves.
