Abstract The feasibility of using ESO for tiny damage localization with the modal parameters of resonant frequencies and anti-resonant frequencies was investigated in this paper. The sensitivity of anti-resonant frequency was afforded, the formulation for damage localization was built, the damage approximation method is given for the slightly damaged structures. The example demonstrated that based on the modal parameters, due to the character of topology optimization, the search performed globally over the entire structure for defects could find the location of the tiny damage exactly.
