...K. Shivaraj; Krishnan Balasubramaniam; C. V. Krishnamurthy; R. Wadhwan A higher order cylindrically guided ultrasonic wave was used for the detection and sizing of hidden pitting-type corrosion in the hidden crevice regions (between the pipe and the pipe supports) without lifting or disturbing...

...Joseph L. Rose; Li Zhang; Michael J. Avioli, Jr.; Peter J. Mudge Long range ultrasonic guided wave inspection is advancing rapidly and is quite commonplace today. Benefits of using longitudinal or torsional modes are being established in special circumstances of improved sensitivity, resolution...

... defects to simulate corrosion damage. Taking advantage of waveguide effects of the reinforcing bars, these specimens were then tested using an ultrasonic approach. Using the same ultrasonic approach, specimens without seeded defects were also monitored during accelerated corrosion tests. Both...
