Damage Mechanics in Metal Forming

Khemais Saanouni is Professor of applied and computational mechanics at the University of Technology of Troyes (France), where he founded and leads a research group working on advanced modeling in virtual metal forming. He teaches the theoretical and computational nonlinear mechanics with application to metal forming by large inelastic strains with ductile damage and is the author or co-author of more than 200 scientific publications with around 80 papers in major peer-reviewed journals in the field of applied and computational mechanics.
