Dynamic amplification analysis in acoustic wave propagation problems subject to time-variable loads

Resumo

In this work, the formulation of the direct interpolation boundary element method is applied to evaluate the dynamic behavior of continuous acoustic systems subject to the excitation of time variable loads. In such a condition, the temporal variation of the load may be close to some of the system's natural frequencies, and the evaluation of dynamic amplification and damping effects is very important. Physically, the analysis undertaken in this work provides an excellent indication of the dynamic behavior of a continuous system subject to pressure waves, which can be an aqueous medium or any seismic medium. In numerical terms, the simulations carried out show the robustness of the chosen technique in solving acoustic wave propagation problems compared to other methods.
