<p>We proposed a nondestructive testing method based on a visualization technique of the dynamic motion in a target structural component. The motions were excited by hammering at multiple points, and received at a fixed position. Using the reciprocity theorem in elastodynamic problems, we visualized the dynamic motion of the structural component. In the visualization, the significant deformation was observed when a wall thinning part was located just at the position of an antinode in a bending vibration mode. Therefore, the use of the guided wave of bending mode was applied to the detection of wall thinning at unknown locations. By choosing an appropriate guided wave mode, it was shown that the location of the wall thinning can be evaluated successfully.</p>
