Severe deformation in crystal plasticity context of a 304L polycrystal with CIMLib - FE and optimized level-set framework - in collaboration with the MSR team [PhD R. Boulais-Sinou]





 

3D modeling in a finite element/level-set numerical framework [PhD B. Scholtes] of grain boundaries pinning by second phase particles during Inconel718 annealing - in collaboration with the MSR team [Metal Physics research unit]





 

3D grain growth modeling for 304L thanks to a level-set framework in a finite element context [Phd B. Scholtes] - in collaboration with the MSR team [Metal Physics research unit]





 

Multi-scale modeling of textured polymer molding - Application to the polymer systems of drug delivery [Postdoc R. Nakhoul]



In the macroscopic modeling, the evolution of the polymer is followed during the injection of a small piece under a high flow rate of 20 cm³/s.
The polymer temperature and viscosity are also followed as functions of time.


The microscopic modeling is performed on a longitudinal section in the piece thickness. Both the cavity filling and thermal transfers between the mold and the polymer are presented.
The cavities are filled one after the other along the polymer evolution. The core remains hot while the skin cools down due to the mold temperature. The microscopic modeling is necessary in order to inspect closely and precisely the different scenarios of the micro-cavities filling, the thermal transfer between the mold and the polymer, the thickness of the solidified zone, the impact of the micro-cavities on the macroscopic scale ... …



 

Development of a FE/level-set strategy in order to model ductile damage at the microscopic scale [PhD M. Shakoor]



Debonding at the inclusions/matrix interfaces in traction conditions

Porosities coalescence in shear conditions


 

This video presenting the contraction of a newtonian flow charged with fiber of high aspect ratio. The coupling of fiber orientation to the velocity-pressure solver shows the rising of re-circulation that are not present if the fibers are off. This, allows us to see the influence of the fiber on the flow [PhD L. Salazar]




 

FE modeling of shot peening process - Prediction of the residual stress [PhD A. Toufayli]



mono-impact configuration


multi-impacts configuration

 

2D grain growth simulation in a high anisotropy context and a FE/level-set framework : grain boundaries are colored according to their different misorientation angles. The two red boundaries in the initial microstructure are coherent twin boundaries. During the simulation, they differ from the coherent plan driven by the migration of adjacent regular boundaries and become incoherent. [Phd Y. Jin] - in collaboration with the MSR team. [Metals Physics research unit]





 

2D FE modeling of abnormal grain growth in a superalloy by taken into account explicitly the second phase particles [PhD A. Agnoli] - in collaboration with the MSR team [Metals Physics research unit]




 

3D FE modeling of the interaction between a grain boundary (in red - 2D cut) and a spherical second phase particle (Zener pinning phenomenon) - in collaboration with the MSR team [Metals Physics research unit]
