Dr. Jean-Robert Clermont has been Emeritus Research Director at CNRS (National Centre for Scientific Research, France) since 2010 and continues to collaborate with the Laboratoire Rhéologie et Procédés de Grenoble, CNRS/Université Grenoble Alpes (UGA)/Institut National Polytechnique de Grenoble (INP Grenoble). He is Civil Engineer, has obtained a master’s degree in Applied Mathematics and a Ph D. and presented a State Thesis, at Grenoble University. He has taught Continuum Mechanics, Mathematics and Computational Methods at a master’s level.His research focuses on theory, applications and numerical simulations in the field of rheology. He proposed the so-called stream-tube method, in connection with problems encountered in nonlinear behavior of materials. Dr. Clermont has advised more than 30 students in Ph.D. and master’s degrees. He has presented plenary talks at international conferences and has published research results in high-level international periodicals.Professor Amine Ammar is Full Professor of Computational Mechanics at Arts & Métiers Paris Tech. He obtained his Ph.D. Thesis in 2001 at the Paris VI University – ENS Cachan. In 2006, he obtained his French degree to supervise research (HdR), with a specialty in mechanics. In 2009, he was awarded the Scientific prize of the European Association of Material Forming awarded in the 12th Esaform Conference and the French Jean Mandel prize awarded in the 19th CFM Conference. His research has been on various topics: model reduction of PDE resolution, proper generalized decomposition, kinetic theory of polymers and suspensions and short reinforced fiber composite processing, among them.
