In order to detect back surface defects in a plate, the surface strain distribution is visualized by use of piezoelectric thin film. When the plate with a back surfa ce defect is deformed, the resultant strain distribution in the front surface reflects the defect. Such surface strain distribution can be obtained from the electric potential distribution on the piezoelectric film mounted on the front surface. The purpose of this paper is to detect the defects by measuring the electric potential distribution...
