Boyd Professor at the Louisiana State University, in the Department of Civil and Environmental Engineering. Voyiadjis is a Foreign Member of the Academia Europaea, the European Academy of Sciences, and the European Academy of Sciences and Arts. He is a Foreign Member of both the Polish Academy of Sciences, and the National Academy of Engineering of Korea. He is the recipient of the 2008 Nathan M. Newmark Medal of the American Society of Civil Engineers He is a Distinguished Member of the American Society of Civil Engineers; Fellow of the American Society of Mechanical Engineers, the Society of Engineering Science, the American Academy of Mechanics, and the Engineering Mechanics Institute of ASCE; and Associate Fellow of the American Institute of Aeronautics and Astronautics. Voyiadjis' primary research interest is in plasticity and damage mechanics of metals, metal matrix composites, polymers, 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.
He has 2 patents, over 364 refereed journal articles, and 23 books (12 as editor) to his credit. He has given over 420 presentations as plenary, keynote, and invited speaker as well as other talks. Over 68 graduate students (39 Ph.D.) completed their degrees under his direction.
