A 3D finite element modeling of the orthogonal turning process was curried out in the current study. It aims to carefully investigate the mechanisms controlling the chip segmentation and the crack propagation direction in ... -
Article dans une revue avec comité de lectureLE, Viet-Duc; PESSARD, Etienne; MOREL, Franck; (Elsevier, 2020)
This work is focused on the influence of defects on scatter and statistical size effect of Ti-6Al-4V alloy fabricated by the SLM process. A vast fatigue test campaign has been undertaken, for two surface conditions (as-built ...

In the present work, a phase field damage model is developed to address the numerical simulation of brittle fracture. This model successfully captures some important aspects of crack propagation, including crack branching ...

A generic methodology to deal with the mechanics of beams and shafts with cracks is presented. The elastic energy of the system under static loading is written in a comprehensive manner to remarkably reduce the 3D computations ...

Article dans une revue avec comité de lectureAMMAR, Amine; CHINESTA SORIA, Francisco (Elsevier Masson, 2019)
The present work aims at performing a molecular dynamics modeling of suspensions composed of flexible linear molecules. Molecules are represented by a series of connected beads, whose dynamics is governed by three potentials: ...

When addressing the flow of concentrated suspensions composed of rods, dense clusters are observed. Thus, the adequate modelling and simulation of such a flow requires addressing the kinematics of these dense clusters and ...
