概要
Guided wave has been applied to a wide variety of non-destructive testing for a plate, bar and pipe, among others. In this study, we propose a wireless sensing system for the guided wave testing in structural components. The three-dimensional motion of the structural component can be visualized using the measured guided waves at a fixed position, which are individually excited at various positions. This method is based on the elastodynamic reciprocity theorem. Here, the validity of the visualization method of the guided wave is investigated with an I-beam metal specimen. Also, the wave propagation mode extracted from the visualization result is compared with a numerically calculated dispersion curve.
