Classical IR ultrasonic thermography is based on applying a relatively powerful ultrasonic stimulation to test objects. Attempting to expand an inspection area by further increasing ultrasonic power may lead to sample damage, particularly, at a stimulation point. The recently proposed low-power resonant ultrasonic vibrothermography method involves an individual approach to the inspection of materials being based on a detailed analysis of vibrations on the sample surface in a wide range of acoustic frequencies. The determination of defect resonance frequencies enables efficient transfer of acoustic wave energy into a defect area and further transformation of this energy into heat due to intensive plastic deformations and internal friction. This paper contains the results of applying low-power ultrasonic IR thermography to detecting impact damage in graphite epoxy composite by using techniques of laser vibrometry and IR thermography.
