Interaction of Ultrasonic Waves with Composite Plates.

Abstract

During the second year of our reporting period we continued our close cooperation with the NDE Branch on the Material's Lab at Wright-Patterson Air Force Base. For our part, we continued developing analytical and computational methods on the modeling of the mechanical behavior of fibrous composites for applications in the NDE field. Specifically, we extended our theoretical models which were developed to describe the behavior of single unidirectional fiber-reinforced plates, to more general plates. These included single and multilayered plates. For the single laminated plate the solutions are extended for arbitrary azimuthal angles and hence resulted in three dimensional analysis.
