Adaptive Testing for Nondestructive Evaluation of Degraded Materials

Developing Raman Spectroscopy for the Nondestructive Testing of Composite Materials

The goal of this research is to examine the potential of Raman spectroscopy as a method of condition assessment for carbon fiber composite materials. Carbon fiber composites are used in high performance situations such as overwrapping of composite over-wrapped pressure vessels (COPVs) in aerospace applications and hydrogen and natural-gas transportation systems. The composites will play a large...

Novel Integrated Nondestructive Testing Methodology for Detection and Evaluation of Corrosion in Cement-Based Materials

Millimeter Wave Doppler Sensor for Nondestructive Evaluation of Materials

INTRODUCTION Resonance modes are intrinsic characteristics of objects when excited at those frequencies. Probing the resonance signatures can reveal useful information about material composition, geometry, presence of defects, and other characteristics of the object under test. Vibration spectra can be measured remotely with high degree of sensitivity using a millimeter wave (mmW) Doppler senso...

Nondestructive Testing and Evaluation of Steel Bridges

Nondestructive evaluation (NDE) is a means of evaluating structural components without damaging them. It can be used to evaluate structural systems, as well as specific structural components. Nondestructive testing is particularly useful for evaluating inservice bridges, since the bridges can remain in tact and open to traffic during the inspection and evaluation period. The NDE methods discuss...
