N2 - In this paper, we present an advanced computational approach for modeling layered structures.The structures can be horizontally layered plates or layered half-spaces.The materials can be multi-field coupled, i.e., thermoelastic, poroelastic, and magnetoelectroelastic coupled, but require that they are transversely isotropic (TI) with material symmetry axis along the layering direction.This advanced approach is based on the recently constructed Fourier-Bessel series (FBS) system of vector functions and the dual-variable and position (DVP) method.While the DVP is for propagating the layer matrix from one layer to the next with unconditional stability, the FBS vector system is to 1) represent the general deformations/waves with distinguished deformation/wave types, and 2) pre-calculate the expansion coefficients as Love numbers and then use them later for massive simulation of the involved problem.Three typical examples are presented to demonstrate the accuracy and efficiency, as compared with the existing approaches.These are:faulting (or dislocation) in a layered earth, soil-structure interaction, and transient wave propagation in a near-surface earth profile.
