Non-destructive interrogation techniques for highly heterogeneous composite materials

Abstract

We propose to continue collaborations with scientists at AFRL/RX, led by Amanda Criner, and a research group at NCSU, led by H.T. Banks. We have been using advanced techniques (probability distributions estimated using the Prohorov Metric Framework in which the infinite dimensional optimization is reduced to a finite dimensional optimization using an approximating space composed of linear splines). The investigation seeks to identify thermal degradations using probabilistic models in reflectance spectroscopy in response to frequency sweeps. Our findings to date suggest we should expand our efforts using absorption and transmission properties of materials, in addition to the reflectance spectroscopy. We propose both non-invasive and non-destructive interrogation techniques.
