Abstract
The non-destructive inspection is important to manage large structures for a long term. But accuracy of damage detection depends on skill of an inspection engineer. So, damage detection method independent of skill of engineers is required. In order to detect damage of structures without omission, pattern recognition is proposed as a method for automatically detecting damage. However it is not realistic because this method needs enormous scales database each target structure. As other method, in contrast, it is proposed that is based on dynamical model and analytically numerical calculation. Method of damage detection in this research use vibration characteristic of damage structure acquired by inspection, and derive structure that accord with characteristic of damage structure by topology optimization.
