Wave propagation in infinite or unbounded domains is often encountered in scientific and engineering applications. Theoretical fundamentals and applications of a new numerical model which has the ability to simulate such wave propagation are presented. Attention is focused on linear waves in ideal fluids and elastic domains. Wave propagation based on scalar and vector wave equations, as well as fluid-structure interaction and soil-structure interaction is numerical simulated. The model is based on a coupled finite element/scaled boundary finite element method (FEM/SBFEM). While the FEM maps the near-field, under the immense variety of non-reflecting boundary conditions the SBFEM, developed by Wolf and Song, was chosen. It has some unique features: reduction of the spatial dimension by one without requiring a fundamental solution, no discretisation of free and fixed boundaries and interfaces between different materials, and influence of the infinite far-field could be stored in the form of matrices for further simulations (e.g., different load cases). Benchmark examples show the efficiency and accuracy of the proposed algorithm. Finally, covered fields of applications are: acoustics, dynamic behaviour of offshore wind turbines, and seismic analysis of buildings including soil-structure interaction.

Wave Propagation in Infinite Domains: The goalsof this workare to presentthe theoretical fundamentalsandto demonstrate the applications of a new numericalmodel which has the ability to simulate the wave propagation in in nite domains. Wave propagation Wave motions are fascinating physical phenomena with important practical appli- tions. Physicists and engineers are interested in the reliable simulation of processes in which waves propagatein solids or uids. The effect of waves is familiar to eve- one, e. g. , transmission of sound or radio waves, vibrations due to traf c or constr- tion work, or water waves. From all wave types in nature, here, attention is focused only on linear waves in ideal uids (e. g. , acoustics) and elastic domains. Acoustic waves (sound) are small oscillations of pressure in a compressible ideal uid (aco- tic medium). These oscillations interact in such a way that energy is propagated through the medium. The governing equations are obtained from fundamental laws for compressible uids, whereas in an elastic medium, waves propagate in the form of oscillations of the stress eld. This work deals with theoretical and practical - sues arising in the computational simulation of wave propagation based on scalar and vector wave equations, as well as uid-structure interaction and soil-structure interaction. While each class of problemshas its distinctive features, there are und- lying similarities in the mathematical models, leading to similar numerical effects in computational implementations.
