Communication avec acte(Technische Universität Darmstadt, 2013)For many decades ArcelorMittal has been developing solutions to enhance machinability of high strength steels for automotive parts. Many well-known metallurgical solutions create or retain inclusions in the metal and then ...

Article dans une revue avec comité de lecture(Wiley, 2014)The determination of forming limit strains in sheet metal forming industry is a useful way for quantifying metals in terms of formability. However, such forming limit diagrams (FLDs) remain very difficult to obtain ...
-
Article dans une revue avec comité de lecture(Trans Tech Publications, 2013)A physically based elasto-visco-plastic constitutive model is presented and compared to experimental results for a DD14 mild steel. The model requires significantly fewer material parameters compared to other visco-plasticity ...
-
Communication avec acte(Wiley, 2012)In this paper, the performance of the solid-shell finite element SHB8PS is assessed in the context of sheet metal forming simulation using anisotropic elastic-plastic behavior models. This finite element technology has ...

Communication avec acte(Association Française de Mécanique, 2007)Dans cet article, une modélisation des différentes phases (ferrite, perlite etc.…) d’un acier multiphasé est proposée moyennant une loi phénoménologique à base physique. La description unifiée du comportement viscoplastique ...

Article dans une revue avec comité de lecture(Techno-press Ltd, 2011)The formulation of a six-node solid-shell called SHB6, which is a linear, isoparametric element, is discussed. An eigenvalue analysis of the element stiffness matrix is first carried out. Several modifications are introduced ...
