Quadratic solid‒shell elements for nonlinear structural analysis and sheet metal forming simulation Article dans une revue avec comité de lecture;
CHALAL, Hocine; ABED-MERAIM, Farid (Springer Verlag, 2017)
In this paper, two quadratic solid‒shell (SHB) elements are proposed for the three-dimensional modeling of thin structures. These consist of a twenty-node hexahedral solid‒shell element, denoted SHB20, and its fifteen-node ... -
Article dans une revue avec comité de lecture;CHALAL, Hocine; ABED-MERAIM, Farid (Emerald, 2017)
This paper proposes two linear solid‒shell finite elements for the three-dimensional modeling of thin structures in the context of explicit dynamic analysis. These solid‒shell formulations, which are extensions of their ...

Article dans une revue avec comité de lectureCHALAL, Hocine; ABED-MERAIM, Farid (MDPI, 2017)
In this work, three numerical necking criteria based on finite element (FE) simulations are proposed for the prediction of forming limit diagrams (FLDs) for sheet metals. An elastic–plastic constitutive model coupled with ...

Article dans une revue avec comité de lectureCHALAL, Hocine; ABED-MERAIM, Farid (Argentinean Association of Computational Mechanics, Brazilian Association of Computational Mechanics, Mexican Association of Numerical Methods in Engineering and Applied Sciences, 2017)
In this paper, forming limit diagrams (FLDs) for an aluminum alloy are predicted through numerical simulations using various localized necking criteria. A comparative study is conducted for the FLDs determined by using the ...

Article dans une revue avec comité de lectureCHALAL, Hocine; ABED-MERAIM, Farid (MDPI, 2018)
In the current contribution, prismatic and hexahedral quadratic solid–shell (SHB) finite elements are proposed for the geometrically nonlinear analysis of thin structures made of functionally graded material (FGM). The ...
