Abstract

The ability to simultaneously measure a homogeneous, isotropic pipe’s elastic properties and wall thickness from its known mass density, outer diameter and the cut-off frequencies of three ultrasonic guided wave modes is demonstrated for a typical steel pipe. This inverse procedure is based upon simulated results computed by using an efficient Semi-Analytical Finite Element (SAFE) forward solver. The Young’s modulus, shear modulus, and wall thickness agree very well with those found from conventional but destructive experiments. On the other hand, Poisson ratios agree within their assessed uncertainties.
