| Research Abstract |
Attempts were made to develop a vibration-based damage detection method using chaotic excitation and to investigate the feasibility of damage detection method with no reference data. It was observed that the proposed system could detect damage location through comparisons with attractor obtained before or after the damage. Numerical results also demonstrated that the proposed method can make it possible to detect the damage location without using any reference data under some conditions of the observed structures.
