Patent attributes
A method for determining the health of a structural element. The method includes providing a plurality of transducer elements arranged and disposed to permit measurement of vibration generated by at least one of the transducer elements at one or more of the other transducers elements. Vibration is induced with at least one transducer element. Vibration is measured at least one other transducer element, where the measured vibration corresponding to a vibratory path. At least one damage index value is calculated for each vibratory path in response to the measured vibration. At least one damage image is generated in response to the damage index value. The damage image assigns damage index values to each vibratory path. A damage location is determined from the damage image.
