Abstract
The methodology to trap the vibrational energy of an axially polarized surface-shear wave (axial-shear wave) in a stepped cylindrical rod is presented. The central part of the rod where the resonance vibration was trapped had a slightly larger diameter. The magnetostriction effect of steel enabled us to generate and detect the resonance with noncontacting. An approximated analysis was used to derived a resonance equation and displacement distribution of trapped axial-shear-wave modes. The displacement was measured along the axial direction and it exponentially decreased with the distance from the center. This trend agreed with the theoretical calculation.
