| Abstract: | Frequency response method used in Structure Health Monitoring (SHM) system is discussed in this article. The effect of perforation and delaminate damage to the structure's dynamic characteristic was analyzed by FEM. RBF Neural Network was used to classify and locate the damage, and the result is properly well. The feasibility and the role of frequency response method (FRM) in SHM system was indicate, some other notice of this method was discussed too. |
