Abstract Sonic infrared (IR) is a rapidly developing nondestructive evaluation technique for detecting and estimating the length of fatigue cracks in aircraft components. In this study, a spatial and temporal forward analytical solution of a simple 2D heat diffusion model is developed assuming uniform frictional heat generation along the crack. This model not only captures the temperature rise while applying the excitation load, but also captures the temperature decay after the excitation load… CONTINUE READING
