## Abstract This paper develops a finite element scheme to generate the spatialβ and timeβdependent absorbing boundary conditions for unbounded elasticβwave problems. This scheme first calculates the spatialβ and timeβdependent wave speed over the cosine of the direction angle using the Higdon's on
We construct global artificial boundary conditions (ABCs) for the numerical simulation of wave processes on unbounded domains using a special nondeteriorating algorithm that has been developed previously for the long-term computation of waveradiation solutions. The ABCs are obtained directly for the
