CHALAL, Hocine; ABED-MERAIM, Farid (ACMA, 2016)
In this work, ductility limits of metallic materials, associated with the occurrence of strain localization, are predicted using the GTN damage model coupled with bifurcation theory. The resulting approach is implemented ... -
Article dans une revue avec comité de lecture(Springer, 2021)The use of shape memory alloys for micro-actuators constitutes a field of application in which copper-aluminum-based alloys find their usefulness because they can reach higher activation temperatures and are easier to ...

Article dans une revue avec comité de lecture;FROMENTIN, Guillaume; VIPREY, Fabien; ; D’ACUNTO, Alain (Society of Manufacturing Engineers, 2021)
Inconel 718 is widely used in aircraft industry due to its properties. Nevertheless, its mechanical and chemical properties make it hard-to-cut. As a consequence, additive manufacturing is developed in order to get near ...

Article dans une revue avec comité de lecture; ; ; ;PESSARD, Etienne (Elsevier, 2021)
This work is focused on the effect of natural defect on the fatigue resistance of a laser powder bed fusion additively manufactured Ti-6Al-4V titanium. To reveal the fatigue strength variability and its sensitivity to the ...

Article dans une revue avec comité de lecture;BERVEILLER, Sophie; MERAGHNI, Fodil; ; (Springer Science and Business Media LLC, 2021)
In this work, a (TiHfZr)(NbTa) 26 (%at) high-entropy quinary alloy has been developed especially for high-temperature superelastic applications and studied over a large range of temperatures. The mechanical properties of ...

Conférence invitéeABED-MERAIM, Farid (2018)
In the literature dealing with plastic instabilities in general, many instability criteria have been developed, and some of them have been extensively applied to sheet metals to investigate their formability limits. ...

Communication sans acte;JEBAHI, Mohamed; ABED-MERAIM, Farid (2021)
Strain localization is an important plastic instability process occurring prior to fracture. It is usually observed in the form of narrow bands of intense plastic shear strain in deformed bodies undergoing severe inhomogeneous ...
