ZHOU, Shuai; BEN BETTAIEB, Mohamed; ABED-MERAIM, Farid (2024-05)
Accurate predictions of ductility limits play a crucial role in product design and manufacturing, offering substantial cost reductions in development. In this investigation, attention is focused on the prediction of ductility ... -
Communication avec acteALTSHUL, Grigorii; GUSKOV, Mikhail; BALMES, Etienne; LORONG, Phillippe (2024-09)
This article presents a novel modal analysis method for investigating the dynamic behavior of milling robots. The proposed method utilizes inertial forces generated by an unbalanced tool rotating on the spindle to excite ...

Communication avec acte;BEN ZINEB, Tarak; ABED-MERAIM, Farid; (2003-09-02)
The elastic-plastic behavior of polycrystals is studied. A single-crystal constitutive law is defi ned thanks to crystalline plasticity in the large strain framework. The self-consistent scheme is adopted to obtain macroscopic ...

Communication avec acteBALAN, Tudor; ABED-MERAIM, Farid; HADDAG, Badis (2004-05)
Deep drawing is a forming process widely used to obtain parts of suited shape from sheets initially flat. These sheets are obtained generally by rolling and thus present an initial orthotropic anisotropy. Several behaviour ...

Communication avec acteCHALAL, Hocine; ABED-MERAIM, Farid (Luso Impress S.A. Publisher, 2015)
In this work, two numerical ductile fracture criteria based on finite element (FE) simulations are proposed for the prediction of ductile fracture limits (DFLs) for sheet metals. An elastic–plastic model coupled with the ...

Article dans une revue avec comité de lectureABED-MERAIM, Farid; (Elsevier BV, 2002-04)
This paper presents the formulation of a new adaptive shell element. This is an eight-node brick element in which one chooses a special direction denoted ‘‘thickness’’. The element is an assumed-strain element based on the ...
