PERRY, Nicolas; MONTEMURRO, Marco (2019)
In this work, a new semi-automatic surface reconstruction procedure is proposed. The main goal of the method is to reconstruct the boundary surface of a triangulation obtained as a result of a topology optimisation ... -
Article dans une revue avec comité de lecture; ;MONTEMURRO, Marco (Springer Verlag, 2019)
This study deals with the problem of the least-weight design of a lattice structure subject to constraints of different nature. To face this problem, a general multi-scale optimisation procedure is proposed. This approach ...

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 ...

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 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 lecture(Elsevier, 2013)In the aim of producing fully organic bionanocomposite based on poly(lactide) (PLA), cellulose nanowhiskers (CNW) were grafted by n-octadecyl-isocyanate (CNW-ICN) applying an in situ surface grafting method. The compatibilizing ...
