Resume

Dr. Carpenter is a metallurgical engineer specializing in analysis of fractures, corrosion failures, and weld failures. 

Dr. Carpenter has also been responsible for the evaluation of failed components from automobiles, aircraft, gas and water systems, and bearing assemblies.  He has taught a course on x-ray diffraction and x-ray fluorescence.

Dr. Carpenter has conducted research in the welding of ferrous and nonferrous materials.  His experience includes joint design, filler metal selection and parameter specification for joining processes.  His metallurgy experience provides a strong background for assessing weld metal defects and failures. 

Dr. Carpenter has worked extensively with the evaluation of plumbing component fractures and corrosion failures.  He has also evaluated fire effects on steel structures. Other joining specialties include brazing and soldering using torch or vacuum furnace techniques.  Dr. Carpenter has performed extensive mechanical testing to characterize material suitability for specific applications. 

Testing experience includes proof loading, fatigue testing, ultimate and yield strength determination.  Other analytic specialties include hardness testing of materials as well as transmission (TEM) and scanning electron microscopy (SEM), x-ray photoelectron spectroscopy (XPS) and x-ray diffraction (XRD).  Extensive analysis and design experience allows him to evaluate failed components in terms of in service loading.
