Abstract:

The final report for Diagnosis and Prognosis of Filament Wound Components Subject to Combined Loads Using Nonlinear Signal Processing of Standing and Traveling Waves is presented here in the form of a journal article. This article summarizes the approach, test procedures, analysis methods, results, and conclusions associated with the study of frequency domain techniques for characterizing helmet and helmet padding performance through nondestructive evaluation. Upon approval, this article will be submitted to an appropriate journal for publication consideration.
