Wave propagation in unbounded layered media with a new formulation of Axisymmetric Scaled Boundary Finite Element Method (AXI-SBFEM) is derived.Dividing the general three-dimensional unbounded domain into a number of independent two-dimensional ones, the problem could be Speciality Boxes 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 Donation literature.Numerical examples indicate the applicability and high accuracy of the new method.
