Article dans une revue avec comité de lecture(Elsevier, 2017)Biocompatible beta-titanium alloys such as Ti-27.5(at.%)Nb are good candidates for implantology and arthroplasty applications as their particular mechanical properties, including low Young’s modulus, could ...

MERAGHNI, Fodil; ; (SAGE Publications, 2019)
Although both computational and analytical homogenization are well-established today, a thorough and systematic study to compare them is missing in the literature. This manuscript aims to provide an exhaustive comparison ... -
Article dans une revue avec comité de lecture;CHALAL, Hocine; ABED-MERAIM, Farid (SAGE Publications, 2018)
In this paper, the conditions for the occurrence of diffuse and localized necking in thin sheet metals are investigated. The prediction of these necking phenomena is undertaken using an elastic‒plastic model coupled with ...

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 ...

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 lecture;CHALAL, Hocine; ABED-MERAIM, Farid (Elsevier, 2017)
The current contribution proposes two quadratic, prismatic and hexahedral, solid–shell elements for the geometric nonlinear analysis of laminated composite structures. The formulation of the proposed solid–shell elements ...

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 ...
