MERAGHNI, Fodil; (Elsevier, 2019)
This study proposes a micromechanical model based on a modified multi-scale mean field approach that predicts the overall behavior of long fiber reinforced elastoplastic and viscoelastic-viscoplastic composites. The ... -

In the following work, we propose a metallurgical approach to the chip formation process. We focus on a turning application of high strength steel in which chips are produced by adiabatic shear bands that generate cutting ...

Article dans une revue avec comité de lecture;MERAGHNI, Fodil (SAGE Publications, 2019)
This paper deals with mean field multiscale approaches for coated fiber- or particle-reinforced composites under nonlinear strain. The current work attempts to extend Dvorak’s well-known transformation field analysis for ...
