Research Interests

Voyiadjis’ primary research interest is in damage mechanics of metals, metal matrix composites, and ceramics with emphasis on the theoretical modeling, numerical simulation of material behavior, and experimental correlation. Research activities of particular interest encompass macro-mechanical and micro-mechanical constitutive modeling, experimental procedures for quantification of crack densities, inelastic behavior, thermal effects, interfaces, damage, failure, fracture, impact, and numerical modeling. His experience also includes work on modeling of cyclic plasticity for metals and soils, refined theories for plates and shells, and numerical simulation of cone penetrometers and tunnel boring in clay soils.

Dr. Voyiadjis’ research has been performed on developing numerical models that aim at simulating the damage and dynamic failure response of advanced engineering materials and structures under high-speed impact loading conditions. This work will guide the development of design criteria and fabrication processes of high performance materials and structures under severe loading conditions. Emphasis is placed on survivability area that aims to develop and field a contingency armor that is thin and lightweight, but with a very high level of an overpressure protection system that provides low penetration depths. The formation of cracks and voids in the adiabatic shear bands, which are the precursors to fracture, are mainly investigated.

He has over 200 referred journal articles and 15 books (8 as editor) to his credit. Over fifty graduate students (25 Ph. D.) completed their degrees under his direction.  He has also supervised numerous postdoctoral associates. Voyiadjis has been extremely successful in securing more than $10.0 million in research funds as a principal investigator from the National Science Foundation, the Department of Defense, the Air Force Office of Scientific Research, the Department of Transportation, and major companies such as IBM, and Martin Marietta.

He has been invited to give plenary presentations and keynote lectures in many countries around the world. He has also been invited as guest editor in numerous volumes of the Journal of Computer Methods in Applied Mechanics and Engineering, International Journal of Plasticity, Journal of Engineering Mechanics of the ASCE, and Jounal of Mechanics of Materials. These special issues focus in the areas of damage mechanics, structures, fracture mechanics, localization, and bridging of length scales. Dr. Voyiadjis also worked two years in the industry as a senior engineer with Nuclear Power services, Inc., and Ebasco Services Inc.  During that period of time he was engaged in the research and development of stress analysis of nuclear power plants. He was also involved in the development of finite element computer codes in conjunction with the piping analysis of power plants.
