Two analytical modifications of the original viscoelastic time-harmonic Lamb’s problem
expressions are presented with the aim of improving their numerical integration efficiency.
Firstly, a new change of variable in the Lamb’s problem integrands is proposed, which
allows a standardization of the integration sampling vector and a complete spatialfrequency
field solution after performing only one numerical integration/transformation.
Secondly, the Lamb’s problem static integrands are modified and introduced into the
original integrands to reduce their spectral content at high wavenumbers and, therefore,
the sampling vector lengths needed to avoid aliasing.
