This paper applies strain frequency response function (SFRF), presenting crack damage identification index based on change amplitude of SFRF. Crack propagation identification of four corners fixed thin plate experiment system based on fiber bragg grating sensors is established, experiments and analysis are carried out. Results show that: this crack damage identification system can identify crack damage occurs and propagation effectively.
