Scalar-based strain gradient plasticity theory to model size-dependent kinematic hardening effects Article dans une revue avec comité de lecture;
JEBAHI, Mohamed (Springer Verlag, 2021)
A common belief in phenomenological strain gradient plasticity modeling is that including the gradient of scalar variables in the constitutive setting leads to size-dependent isotropic hardening, whereas the gradient of ... -
Article dans une revue avec comité de lecture; ;ABED-MERAIM, Farid (2021)
Buckling and wrinkling of thin structures often lead to very complex response curves that are hard to follow by standard path-following techniques, especially for very thin membranes in a slack or nearly slack state. Many ...

Analysis of Residual Stress Relaxation Under Mechanical Cyclic Loading of Shot-Peened TRIP780 Steel Communication avec acte; ; ; ;BERVEILLER, Sophie; BARRALLIER, Laurent; KUBLER, Regis (Materials Research Forum LLC, 2016)
Shot-peening is a popular mechanical surface treatment used in automotive and aeronautical industries to enhance life duration of mechanical parts by introducing compressive residual stresses. TRIP 780 fatigue type specimens ...

Article dans une revue avec comité de lecture;BEN BETTAIEB, Mohamed; ABED-MERAIM, Farid (Wiley (Holm Altenbach), 2021)
In this paper, we study some qualitative and numerical properties of new equations including the coupled effects of thermal elastic-plastic theory with microtemperatures. We establish the necessary and sufficient conditions ...

Communication avec acte;CHALAL, Hocine; ABED-MERAIM, Farid (ESAFORM, 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 ...

An anisotropic model with linear perturbation technique to predict HCP sheet metal ductility limit Communication avec acte;BEN BETTAIEB, Mohamed; ABED-MERAIM, Farid ; ; ; (2021)
In this paper, hexagonal closed packed (HCP) sheet metal ductility for a viscoplastic material is analyzed by using a linear perturbation technique. It can be used for the analysis of localized necking. This technique is ...

Communication avec acte;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 ...
