The non-destructive testing is significant in the long life operation of large structure such as ships. In the non-destructive testing, the variation in structural characteristics from the original one to the damaged one is used to identify the damage. In this paper, a damage identification method in non-destructive testing is proposed using difference of eigenvalue between the original structure and the damaged one. Damage is specified by topology optimization that minimizes this difference. An optimization algorithm is constructed based on the topology optimization and MMA. The validity and the usefulness of the proposed method are confirmed by several numerical examples.
