  • Method for non-destructively testing construction elements
    Patent number: 4383446
    Abstract: A method of non-destructively testing construction elements accessible from only one side by measuring their resonant oscillations to detect flaws in them without scanning. A test piece (1) is excited with a narrow band ultrasonic oscillation whose frequency is varied; the amplitudes of the resonant oscillations are measured and plotted in an xy coordinate system against the frequency of the exciting ultrasonic oscillations.
