Personal Background | |||
Laurent Dupuy joined the Metals and Alloys group in September 2004
as a postdoctoral fellow. He received his Master's degree in Physics
in 1997 and his Ph.D. degree in Material Science in 2000 from Institut
National Polytechnique de Grenoble, France. His graduate advisors were
Drs. Edgar Rauch and Jean-Jacques Blandin. His thesis is entitled
"Mechanical behavior of an aluminium alloy subjected to severe
elastic deformation". In this experimental work, he built an
Equal Channel Angular Extrusion device and devised a system to measure
quantitatively grain misorientations maps using a TEM. The grain
refinement mechanism during ECAE experiments was analyzed and it
was shown to be closely related the nature and amplitude of the
changes of strain path during severe plastic deformation. He then
worked with Dr. Marc Fivel on discrete dislocation dynamics simulations
with an emphasis on the formation and strength of dislocation junctions
in FCC metals. In 2001 he joined Prof. Rob Phillips at California Institute
of Technology where he pursued his work on junctions strength. He then
worked on an hybrid molecular dynamics/finite element algorithm
with Profs. Rob Phillips, Ron Miller (Carleton University, Canada)
and Ellad Tadmor (Technion, Israel).
In April 2006 Dr. Dupuy accepted a staff position at CEA in Saclay, France. There he continues to conduct research in plasticity. |
