... Abstract Vibrothermography, also known as sonic thermography, sonic infrared (IR), thermosonics, and vibroacoustic thermography, is a nondestructive evaluation (NDE) technique for finding cracks and delaminations through vibration-induced heating. This article describes the four parts...

... and selective excitation configuration of the signal-generation mechanisms in thermal nondestructive evaluation methods. The three widely used approaches to TNDE are surface-excited thermography, vibrothermography, and thermoelastic stress analysis. The article provides information on the common features...

... stress on the surface of a part subjected to time-varying loads. Thermoelastic stress analysis differs from other thermal techniques in that it does not measure heat transfer through a part due to an externally applied excitation, as in pulse thermography or vibrothermography, but instead it measures...
