MERAGHNI, Fodil (Springer Verlag, 2019)
This manuscript provides novel bounds and estimates, for the first time, on size-dependent properties of composites accounting for generalized interfaces in their microstructure, via analytical homogenization verified by ... -
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 ...
