David M. Stepp

Assistant Research Professor

Dr. Stepp's research interests seek to establish the fundamental relationships between the structure of materials and their mechanical properties, as influenced by composition, processing, environment and applied stimulus. His specific research thrusts include novel toughening mechanisms in transparent polymers, fracture of gels, rapid and validated mechanical characterization of very low volumes of material, fracture and failure analysis and prediction, nondestructive evaluation and statistical data analysis. In addition to his faculty appointment, Dr. Stepp serves as the Chief of the Materials Science Division of the U.S. Army Research Office.
