The present study employs an electric voltage change method for the identifications of location and size of embedded delamination cracks of CFRP plates. Measurements of electric voltage change at multiple points are robust against electric resistance change of electrodes, and the method is usually called four-probe method for high precision measurements of electric resistance change. However, our previous analysis showed the method is less sensitive than the method that uses change of electric resistance between the electrodes. In the present study, high precise measurement system of electric voltage change is developed, and the electric voltage measurement method is adopted for identification of embedded delamination location and size. As a result, the electric voltage change method is shown to be useful for the identifications of embedded delamination cracks of CFRP plates.
