Interaction of Ultrasonic Waves with Composite Plates.

Abstract

During the first year of our reporting period we continued our close cooperation with the NDE Branch of the Materials Lab at Wright-Patterson Air Force Base. For our research part, we continued supplying analytical and computational methods on the modeling of the mechanical behavior of fibrous composites for applications in the NDE field. Specifically, we developed theoretical models to describe the influence of fibrous composite's microstructure (both in the forms of dispersive and anisotropic effects) and its gross behaviors. This was verified experimental by using Leaky Wave propagation techniques whereas the scientific group at Wright Patterson continued conducting experimental verification of our modeling. These combined efforts contributed to an advancement of the state-of-the-art regarding the understanding for the ultimate good of developing inspection tools and methods to defects in such materials. As described below our efforts resulted in several presentations and publications in the open literature.
