Application of a Coating Sensor to Aluminum Structural Crack Monitoring
Metal structural crack monitoring is a significant and difficult task for structural health monitoring. A special coating sensor was employed in this study to monitor aluminum structural cracks. The coating sensor was deposited on the hot spots of the aluminum structure by modern surface technology. Fatigue experimental results show that the information of the structural crack origination and propagation can be obtained through analyzing the changes of the electrical conductivity of the coating sensor, and the fatigue performance of the specimen is not obviously changed after the coating sensor deposited on it.
