The purpose of this thesis is to propose novel designs and formulations of different absorbing layers at the boundaries of finite element meshes for the numerical simulation of wave propagation in unbounded 2D and 3D media, in order to deal with complex soil-structure interaction problems in transient dynamics. Three absorbing layers are developed: Rayleigh Absorbing Layer, Kosloff Absorbing Layer and Perfectly Matched Layer (PML). By studying analytically the strong form of elastic wave propagation in each medium, the frequency-independent absorbing ability of Kosloff damping and PML is derived, whereas the attenuation due to Rayleigh damping turns out be frequency-dependent. The interface problem between a non-dissipative elastic medium a...
