Jean-Marie Drezet

Jean-Marie Drezet is a Teaching Professor at École Polytechnique Fédérale de Lausanne (EPFL), working within the School of Engineering's Institute of Materials (IMX). He holds multiple positions including Maître d'enseignement et de recherche at IMX-Gestion, SMX-Enseignement, and the Laboratory of Mechanical Metallurgy (LMM). His office is located at MXG 330 building on the EPFL campus in Lausanne, Switzerland.

Drezet's research focuses on thermomechanical effects in cast metal parts, particularly aluminum alloys. His expertise includes residual stress measurements using neutron diffraction at facilities like PSI-Villigen and ILL-Grenoble, hot cracking phenomena during solidification processes, and the influence of precipitation on residual stresses during quenching of thick aluminum components. His work combines experimental characterization with advanced finite element modeling.

Analysis of his recent publications reveals a consistent focus on residual stress measurement and prediction in aluminum alloys, particularly during casting, welding, and heat treatment processes. His research group extensively uses neutron diffraction for experimental validation and develops computational models to predict stress generation during manufacturing processes. The work spans from fundamental solidification phenomena to industrial applications in aluminum casting and welding.

Drezet has been actively involved in supervising PhD students, with completed theses covering topics such as residual stresses in welded tubular joints, ventricle dilation in hydrocephalus, hot tearing simulation using granular models, and stress generation during quenching of aluminum forgings.

He serves on several committees including the Master admission committee for the Materials section, the IMX library committee, and the editorial committee of Metallurgical Research and Technology journal.
