Analysis and Numeric Formation of a Stationary Wave

Structural health monitoring (SHM) is a system that assesses the state of structures, whether aeronautical, civil or mechanical, and provides a prediction of their remaining life. This has arisen with the need for more economic viability in the monitoring of structures and in fault identification. Thus, this system was defined as a prophylactic, reliable and effective measure against structural failures. This work has as objective the theoretical basis and a bibliographical revision necessary for the execution of the acoustic impedance tube experiment, following the ISO10534-1(1996), as well as numerical simulations. The experimental data are compared with the numerical simulation of the acoustic pressure inside the impedance tube and the artificial immune system is used to characterize the experiment.
