This paper presents numerical techniques for evaluating
integrals of the form
These
integrals arise during the application of the Hankel
transform to pass the displacements of a layered soil profile from the wave number domain to the spatial domain in three-dimensional problems of elastodynamics. The objective here is to obtain solutions with an adequate accuracy from the engineering point of view to the
integrals that arise in a first order formulation of a wave propagation model widely used for layered soils.
