BEN BETTAIEB, Mohamed; ; ; ABED-MERAIM, Farid (EDP Sciences (K. Saanouni), 2016)
A number of parts and components involved in the automotive industry are made of thin bent sheets. Unfortunately, the classical predictions based on traditional Forming Limit Diagrams are not relevant when the strain ... -

In the present paper, Thomason’s criterion is coupled with the well-known Gurson–Tvergaard–Needleman (GTN) damage model and used for the determination of the critical void volume fraction fc , which marks the initiation ...

New high temperature shape memory alloyswith five or more elements are under development and present attractive performances for several functional applications. These active metallic materials are called high entropy and ...

Article dans une revue avec comité de lecture(Elsevier, 2020)Al alloys, despite their excellent strength-to-weight ratio, cannot be used at elevated temperatures because of microstructural instability owing to grain growth and precipitate coarsening, thus, leading to a drastic loss ...

Article dans une revue avec comité de lecture;BEN BETTAIEB, Mohamed; ABED-MERAIM, Farid (Springer Verlag, 2020)
In numerical strategies developed for determining the efective macroscopic properties of heterogeneous media, the efcient and robust computation of macroscopic tangent moduli represents an essential step to achieve. Indeed, ...

Elasto-plastic multiscale approaches are known to be suitable to model the mechanical behavior of metallic materials during forming processes. These approaches are classically adopted to explicitly link relevant microstructural ...
