Characterization of Lamb Wave Damage Interactions for Pseudo Damage Development

Proceedings of the 15th International Workshop on Structural Health Monitoring
In aeronautics delamination damage in composite structures are a crucial factor for the timing of maintenance cycles. Structural health monitoring systems based on ultrasonic guided waves have the potential to find them quickly and consequently save airlines money.

Nonlinear Ultrasonic Damage Characterization of Limestone

Research in Nondestructive Evaluation, 2016
ABSTRACTCharacterization of dolomitic limestone rock samples with increasing levels of damage is presented using a nonlinear ultrasonic approach. Limestone test samples with increasing levels of damage were created artificially by exposing virgin samples to increasing temperature levels of 100, 200, 300, 400, 500, 600, and 700°C for a ninety minute ...

Radiation damage characterization in implanted silica

Radiation Effects and Defects in Solids, 2009
The radiation damage produced in silica glass implanted with Ar+ and Au+ ions at different implantation energies and fluences was depth profiled by positron annihilation spectroscopy. The modification of the sub-nanovoids structure of the glass was investigated by measuring the change in the Doppler broadening of the 511 keV positron annihilation line ...

Nondestructive Damage Characterization of Alumina Ceramics

2009
Abstract : A qualitative evaluation of surface and bulk damage and a quantitative percent damage assessment were used to compare the integrity of several nondestructive characterization techniques. X-ray digital radiography and ultrasound C-scan imaging were compared for their ability to detect damage in aluminum-backed alumina test samples ...

Biochemical Characterization of DNA Damaging Agents

2017
This dissertation describes the biochemical characterization of agents that damage DNA. Compounds of this type can have significant clinical value as chemotherapic agents due to their ability to mediate DNA strand cleavage. A central theme in the Hecht laboratory is to investigate the various interactions between DNA damaging agents and DNA to further ...
