Monitoring of Delamination of the CFRP Beam by the Smart Structure System Using the SI-F Method


Article Preview

The structure with the sensor and the actuator is called Smart Structure. Installation of the sensor and the actuator to the structure enables the automatic damage detection. In this paper, a novel damage detection method called “SI-F method” is applied to the Smart Structure to detect the delamination in the CFRP beam. The artificial delamination in the CFRP is introduced by the out-of-plane bending. CFRP beam will be exited by the PZT actuator, and the strain of the surface will be measured by the strain gauge. As the result, the delamination is successfully detected by varying the condition of the excitation.
