Ultrasonic guided waves are used to inspect an interface for disbonds between a composite layer and an aluminum half space. The hybrid analytical finite element method is used to model the problem which involves generating dispersion curves and wave structures and searching for optimum excitation points for inspection. A physical experiment inspects from on top of the metal in a Rayleigh to leaky Rayleigh wave problem. Detection of the defect is achieved using peak frequency shift and signal difference coefficient as features.
