John Beavers, Ph.D., Director, Failure Analysis

John Beavers, Ph.D., FNACE is the director of Failure Analysis for DNV Columbus. He has directed and contributed to numerous research programs on stress corrosion cracking (SCC) and corrosion and performance of structural materials. These programs have included failure analyses, critical literature reviews, and laboratory and field evaluations of metallic and non-metallic materials. Dr. Beavers has utilized state-of-the-art electrochemical, surface analytical, and mechanical techniques for evaluation of materials performance for different forms of corrosion. Electrochemical techniques used include potentiodynamic polarization, polarization resistance, electrochemical impedance spectroscopy, electrochemical noise, and galvanic current measurements. Surface analytical techniques used include Auger Electron Spectroscopy (AES), X-ray Photoelectron Spectroscopy (XPS), Energy Dispersive X-ray Spectroscopy (EDS), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), electron microprobe, and X-ray diffraction. Mechanical techniques used include elastic and plastic fracture mechanics and dynamic mechanical loading techniques, such as slow strain rate and low cycle fatigue.
