Abstract : Theoretical wave propagation models that treat ultrasonic wave interaction with an adhesively bonded system are developed. These models allow the selection of appropriate ultrasonic transducers for bond inspection analysis. Such problems as a variation in bondline thickness, the presence of density gradients in the adhesive bond and improper surface preparation are treated in detail. Preliminary results indicate that the potential for success appears quite high for obtaining a correlation between a bond performance parameter and some specific ultrasonic test parameter.
