Corrosion of tubing used in black-liquor recovery boilers is a major concern in all pulp and paper mills. Extensive corrosion in recovery boiler tubes can result in a significant safety and environmental hazard. Considerable plant resources are expen

This project developed ultrasonic nondestructive evaluation techniques based on guided and bulk waves in multilayered structures using arrays. First, a guided wave technique was developed by preferentially exciting dominant modes with energy in the l

A theoretical model for the analysis of ultrasonic guided wave mode excitation of a comb transducer with time delay features was developed. Time delay characteristics are included via a Fourier transform into the frequency domain. The phase velocity

Ultrasonic guided wave pipe inspection is most often based on axisymmetric loading around the circumference of the pipe and subsequent longitudinal axisymmetric guided wave propagation in the pipe. Unfortunately, 360° access is not always possible,

Experimental tuning of guided wave modes can be performed to search the dispersion space for modes with optimal detection capabilities. An ability to tune to a mode with maximum flaw sensitivity is essential to effective guided wave inspection of pla
