Introduction for the special Issue: statistical fluid dynamics
Article dans une revue avec comité de lecture
Characterizing complex material consists in establishing the relationship between flow rheology during forming processes and the induced micro-structural state that affects directly the final mechanical properties of the formed parts [...]

Article dans une revue avec comité de lecturePRULIERE, Etienne; CHINESTA, Francisco; AMMAR, Amine; LEYGUE, Adrien; POITOU, Arnaud (Elsevier, 2012)This paper addresses two issues usually encountered when simulating thermal processes in forming processes involving tape-type geometries, as is the case of tape or tow placement, surface treatments, / The first issue ...
On the effective conductivity and the apparent viscosity of a thin rough polymer interface using PGD‐based separated representations Article dans une revue avec comité de lectureAMMAR, Amine; GHNATIOS, Chady; DELPLACE, Frank; BARASINSKI, Anais; DUVAL, Jean-Louis; CUETO, Elias; CHINESTA, Francisco (Wiley, 2020)Composite manufacturing processes usually proceed from preimpregnated preforms that are consolidated by simultaneously applying heat and pressure, so as to ensure a perfect contact compulsory for making molecular diffusion ...
Article dans une revue avec comité de lectureAMMAR, Amine; ZGHAL, Ali; MOREL, Franck; CHINESTA, Francisco (Elsevier Masson, 2015)The analysis of materials mechanical behavior involves many computational challenges. In this work, we are addressing the transient simulation of the mechanical behavior when the time of interest is much larger than the ...
Communication avec acteNASRI, Mohamed Aziz; AGUADO, Jose Vicente; AMMAR, Amine; CUETO, Elias; CHINESTA, Francisco; MOREL, Franck; ROBERT, Camille; EL AREM, Saber (Key Engineering Materials, 2015)Forming processes usually involve irreversible plastic transformations. The calculation in that case becomes cumbersome when large parts and processes are considered. Recently Model Order Reduction techniques opened new ...
Article dans une revue avec comité de lectureAMMAR, Amine; CHINESTA, Francisco; CUETO, Elias; DOBLARÉ, Manuel (Wiley, 2012)Models encountered in computational mechanics could involve many time scales. When these time scales cannot be separated, one must solve the evolution model in the entire time interval by using the finest time step that ...
