DERRIEN, Katell (Elsevier, 2009)
The interaction between humid air and transversely isotropic fiber-reinforced composites with swelling polymeric matrix is considered. A model is proposed for the water saturation level in a polymer when stresses are ... -
Article dans une revue avec comité de lecture(Elsevier, 2011)A three-dimensional heat transfer model was developed to predict the temperature fields, the weld geometry and the shape of the solidified weld reinforcement surface during hybrid laser-MAG arc welding of fillet joints. ...

Article dans une revue avec comité de lecture(Elsevier, 2011)In the hybrid laser-arc welding process, a laser beam and an electric arc are coupled in order to combine the advantages of both processes: high welding speed, low thermal load and high depth penetration thanks to the ...

Article dans une revue avec comité de lecture(IOP Publishing, 2011)Recoil pressure is the principal driving force of molten metal in laser processing in the intensity range of 10^-1 ~ 10^2 MW/cm2. It is thus essential to estimate the recoil pressure in order to describe physical processes ...

Article dans une revue avec comité de lecture(Springer Verlag, 2010)A 3-D transient model based on the numerical resolution of fluid-flow and the heat transfer equations is developped for deep penetration laser welding at high welding speed regime, whic results in the humping phenomenon. ...
