“…The evolution of the coherent wave transmission may be understood by the microstructure's change of the medium. Previous works showed [8,20] that the attenuation mechanism of high-frequency coherent waves in porous granular materials is dominated by wave scattering. The damping can be characterized by the attenuation coefficient α, of the coherent wave displacement field.…”

“…Ultrasonic inspection offers non intrusive in-situ measurements of porous granular materials and has been used for monitoring the sintering process [7,8]. The acoustic properties of these porous materials are in general characterized by the properties of the contact network forming the solid frame, the pore fluid if any, and framefluid interactions [9,10].…”

Elastic properties of high tension bolt are evaluated non-destructively by measuring acoustic longitudinal and shear wave velocities using mode-converted ultrasound. Mode-converted longitudinal and shear waves along bolt are captured to calculate acoustic wave velocities and determine elastic constants such as Young’s modulus and Bulk modulus based on acoustoelasticity. Ray analysis to select a specific mode conversion from longitudinal mode to shear mode is carried out and discussed with experimental results. From experiment results of maximum 5% of measurement error, it is shown that the proposed mode-converted ultrasonic technique is very effective and sensitive enough to characterize mechanical modulus of high-tension bolts quantitatively.
