Abstract

Additional components in displacements of elastic wave fields are those which vanish in the case of propagation of homogeneous plane waves. For P-waves in a homogeneous isotropic solid, these are transverse components. Waveforms in additional components in simple models of non-time-harmonic elastic wave propagation with plane wavefronts are analyzed. It is demonstrated that the models based on homogeneous waves with a transverse structure and on inhomogeneous waves show a qualitative difference. Bibliography: 20 titles.
