  • Apparatus and method for damage detection
    Patent number: 5327358
    Abstract: A method for detecting damage in the structure includes a plurality of steps. These steps include determining first data indicative of pre-damage modal parameters of the structure, determining second data indicative of post-damage modal parameters of the structure, and identifying at least one location of the damage based upon first and second data applied to an indicator function. The damage detection method is capable of localizing damage in the structure, and subsequently estimating the magnitude of such damage, using limited modal information.
