Abstract

An imperfect diffusion bond was modeled as a deterministic nonperiodic distribution of cracks and the reflection and transmission coefficients were calculated for incident plane longitudinal waves. The model calculates the crack-opening volumes for any number of cracks under the action of a normally incident ultrasonic wave. The effect of a neighboring crack is represented by a pair of dipoles at the geometrical center of that crack. The model was verified by comparison with exact results and showed that often only the next nearest cracks have an appreciable influence on the ultrasonic coefficients. The model approximates the reflection and transmission coefficients in terms of the number of cracks per unit length.
