Ultrasonic resonance spectroscopy (URS) utilizes information in the
frequency domain obtained due to the constructive and destructive
interference of elastic waves for nondestructive evaluation of
inspected objects. In a resonance test an ultrasonic tone-burst with
sweeping frequency is applied to an ultrasonic transducer and a
resonance spectrum of the inspected structure is acquired. The
acquired spectrum contains information about the properties of
materials used for the structure and flaws that may be present in it.
Measurement setup: Narrowband ultrasonic spectroscopy can be
used for the NDT of aerospace multi-layered structures. The INT-
Bond-Tester used for this test operate on the principle of exciting a
mechanical resonance in a multi-layered structure. A piezoelectric
probe, excited by a swept frequency signal is coupled to the surface
of the inspected structure using a coupling agent. The instrument
acquires probe’s frequency spectrum in the range of some tens of
kHz to several hundreds of kHz. A resonance in the layered structure
occurs when echoes between two boundaries travel back and forth
due to the difference in acoustic impedances at the boundaries.
