  Modeling guided elastic waves in generally anisotropic media using a spectral collocation method

  , Journal of the Acoustical Society of America, Vol: 137, Pages: 1180-1194, ISSN: 0001-4966

  Guided waves are now well established for some applications in the non-destructive evaluation of structures and offer potential for deployment in a vast array of other cases. For their development, it is important to have reliable and accurate information about the modes that propagate for particular waveguide structures. Essential information that informs choices of mode transducer, operating frequencies, and interpretation of signals, among other issues, is provided by the dispersion curves of different modes within various combinations of geometries and materials. In this paper a spectral collocation method is successfully used to handle the more complicated and realistic waveguide problems that are required in non-destructive evaluation; many pitfalls and limitations found in root-finding routines based on the partial wave method are overcome by using this approach. The general cases presented cover anisotropic homogeneous perfectly elastic materials in flat and cylindrical geometry. Non-destructive evaluation applications include complex waveguide structures, such as single or multi-layered fiber composites, lined, bonded and buried structures. For this reason, arbitrarily multi-layered systems with both solid and fluid layers are also addressed as well as the implementation of interface models of imperfect boundary conditions between layers.

  Reconstruction of Temperature Distribution in a Steel Block Using an Ultrasonic Sensor Array

  , Journal of Nondestructive Evaluation, Vol: 33, Pages: 458-470, ISSN: 1573-4862

  Permanently installed ultrasonic sensors have thecapability of measuring much smaller changes in the signalthan conventional sensors that are used for ultrasonic inspections.This is because uncertainties associated with couplingfluids and positional offsets are eliminated. Therefore it ispotentially possible to monitor the onset of material degradation.A particular degradation mechanism that we are keento monitor is high temperature hydrogen attack; where theamount of damage is linked to a drop in ultrasonic velocitywhich we hope can be monitored for with an ultrasonic array.The changes introduced in the ultrasonic propagation velocityare expected to be of the order of 1 % and in practice theyare observable only from a very limited field of view (i.e. fromthe outside of a pipe) and therefore the reconstruction is challengingto accomplish. In order to explore the feasibility ofthis, we are investigating the reconstruction of a non-uniformtemperature distribution which allows us to quickly evaluatethe sensitivity of our method to small spatial variations inultrasonic velocity of the material. Two reconstruction algorithmswere implemented and their performance comparedin simulated and real measurements. The results of the testswere encouraging: local temperature differences as low as10 ◦C could be detected, which corresponds to a local propagationvelocity change of 5 m/s (0.15 % relative velocitychange).
