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 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 lecture;PRAUD, Francis; ; MERAGHNI, Fodil; ; (Elsevier, 2019)
In this paper, a new thermodynamically-consistent modeling approach, dedicated to welding applications, is presented to describe the phenomenon of hardening recovery in metals during annealing. The constitutive equations ...

Article dans une revue avec comité de lecture; ;ABED-MERAIM, Farid (Elsevier, 2018)
A new numerical technique for post-buckling analysis is presented by combining the Asymptotic Numerical Method (ANM) and the Taylor Meshless Method (TMM). These two methods are based on Taylor series, with respect to a ...

Numerical investigation of necking in perforated sheets using the periodic homogenization approach Article dans une revue avec comité de lecture;BEN BETTAIEB, Mohamed; ABED-MERAIM, Farid (Elsevier, 2020)
Due to their attractive properties, perforated sheets are increasingly used in a number of industrial applications, such as automotive, architecture, pollution control, etc. Consequently, the accurate modeling of the ...
