RESEARCH INTERESTS
- Fundamental elastic guided wave studies and
applications.
Voltage signals from ultrasonic waves scattered from planar media measured
in two-transducer experiments; 3-D voltage calculation separates geometry
and materials influence. Results show equivalence of Gaussian and
piston-radiator beams in pitch-catch matched transducer experiments.
Excellent detailed agreement between theory and measurements is found.
Applications are to leak location in spacecraft and materials characterization
and the reflection of finite acoustic beams and their interaction with
fluid-loaded structures.

- Ultrasonic characterization of composite materials.
Ultrasonic study of the propagation of leaky plate
waves in anisotropic, layered advanced materials for aircraft or naval
applications. Performing extensive experimental measurements of guided elastic
waves in highly inhomogeneous layered composites. Have observed and measured
Floquet behavior in periodic composite plates having as few as two unit cells;
also, studied sensitivity to thickness, elastic properties. We have shown that
Floquet wave solutions form partial wave decomposition of SH waves in periodic
plates. Work is continuing to assess implications for materials inspection and
to construct an inspection protocol.

- Novel uses of NDE in the processing of foods .
By employing NDE methods in novel ways, new applications of NDE technology
in food processing are being developed. The first of these is the
determination of the doneness of bread using air-coupled ultrasonics to
assess the state of polymerization of wheat gluten in the standard
one-pound commercial white bread. The methods investigated here are all
completely compatible with industry-standard commercial moving-belt ovens.
Preliminary results have shown significant promise.
