Abstract
This paper shows the applicability of data-driven model identification to describe guided wave propagation in composite structures. The model identified can be useful to predict waveform or further conditions considering the dynamics of wave propagation in composites media, mainly when the geometry or boundary conditions are complex and make it very difficult to propose an analytical model. Thus, the main purpose of this paper is to use a simple autoregressive with exogenous terms model to fit the experimental data assuming different frequencies of excitation and the effect of temperature changes. An example using a composite plate is performed in this paper to show the steps and applicability. After these analyses, the results obtained demonstrate the practical benefits of the black-box model for modeling of guided wave propagation in complex composite structures for aeronautical applications.

Notes
Guided wave can be defined as an elastic wave generated that propagates confined by the boundaries of the structures. The term guided is due to the direction where the wave follows.
Only PZT1 operates as an actuator, while others operate as sensors.
When \(i=1\), it is the input signal, i.e., \(u=y_1\).
\(n_a>n_b\) for online procedures in causal systems.
