CHALAL, Hocine; ABED-MERAIM, Farid (2016)
In this work, an elastic–plastic model with Hill’48 anisotropic yield surface is coupled with the continuum damage mechanics theory and combined with the bifurcation analysis, in order to predict strain localization in ... -
Communication avec acteCHALAL, 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(Elsevier BV, 2022)In this paper, an original probabilistic micromechanics damage framework involving multi-deformation mechanisms, based on the modified Mori-Tanaka and Transformation Field Analysis (MT-TFA) techniques, is developed to ...

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. ...

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 ...

Communication avec acteCHALAL, Hocine; ABED-MERAIM, Farid (ACEX, 2016)
In this paper, forming limit diagrams (FLDs) for an aluminum alloy are predicted through numerical simulations using various localized necking criteria. A comparative study is conducted for the FLDs determined by using the ...

Article dans une revue avec comité de lecture;CHALAL, Hocine; ABED-MERAIM, Farid (Elsevier, 2020)
During the last decades, a family of assumed-strain solid-shell finite elements has been developed with enriched benefits of solid and shell finite elements together with special treatments to avoid locking phenomena. These ...
