Dividing the general three-dimensional unbounded domain into a number of independent two-dimensional ones, the problem could be solved by a significant reduction in required storage and computational time. The equations of the corresponding Axisymmetric Scaled Boundary Finite Element (AXI-SBFE) are derived in detail. For an arbitrary excitation frequency, the dynamic stiffness could be solved by a numerical integration method. The dynamic response of layered unbounded media has been verified with the literature. Numerical examples indicate the applicability and high accuracy of the new method.}, keywords = {Axisymmetric Scaled Boundary Finite Element Method,Fourier Series,Layered System}, url = {https://ceij.ut.ac.ir/article_76791.html}, eprint = {https://ceij.ut.ac.ir/article_76791_d83f8ea6c026db1d1f2bb96d415991ba.pdf} }
