This contribution deals with the use of coupled Rayleigh-like waves for the remote detection of defects in stiffened plates similar to aerospace structures, where access is restricted by regularly spaced features such as stiffeners or stringers. Selecting appropriate excitation frequency and position, it is shown experimentally that a significant part of the energy can be transmitted past multiple obstacles, which act as a band-pass filter. Using a standard Rayleigh angle beam wedge transducer… CONTINUE READING
