Forced anti-plane vibrations at the surface of an inhomogeneous half-space
Abstract The dynamic response of an inhomogeneous, linear-elastic half-space to a time-harmonic tangential line force on the surface is examined. The mass density is assumed to be constant and the shear modulus to increase continuously with depth according to a function which is bounded at infinity. The displacement distribution at the surface is derived by applying the classical Fourier transform method and residue integration. The corresponding solution for the homogeneous half-space is recovered as a special case. Further the contributions of the particular SH-surface wave modes to the total displacement are compared for realistic soil profiles and frequencies.
