Michel Rappaz
Après un doctorat en physique du solide (1978) de l’Ecole Polytechnique Fédérale de Lausanne (EPFL), un post-doc à Oak Ridge National Laboratory, Michel Rappaz rejoint l’Institut des matériaux de l’EPFL en 1981. Après un passage de deux ans dans un bureau d’ingénieurs, il revient à l’EPFL en 1984 où il est nommé Professeur titulaire en 1990, puis Professeur ordinaire en 2003. Après sa retraite de l’EPFL en 2015, il est actuellement Professeur émérite et consultant indépendant auprès de divers centres de recherche et industries.
Ses principaux centres d’intérêt sont les transformations de phase et la solidification, en particulier le couplage des aspects macroscopiques de transferts de chaleur et de masse à l’échelle des procédés avec les aspects microscopiques de germination-croissance des microstructures et des défauts. Parmi ses diverses réalisations, on peut mentionner le développement d’Automates Cellulaires couplés avec la méthode d’Eléments Finis (modèle CAFE) pour la prédiction des structures de grains en solidification, le développement de modèles granulaires pour la fissuration à chaud, l’application de la méthode de champ de phase pour la compréhension de diverses microstructures, la découverte de la germination assistée dans certains alliages par des phases quasicrystallines, ainsi que de nombreuses études touchant aussi bien les aspects fondamentaux de formation des structures que des aspects plus appliqués des procédés.
Certains modèles développés dans son laboratoire ont été commercialisés par une spin-off fondée en 1991 (Calcom SA), faisant partie actuellement du groupe français ESI. Michel Rappaz a initié en 1992 un cours annuel de formation continue en solidification, suivi à ce jour par plus de 900 participants venant d’une quarantaine de pays. Il collabore actuellement avec une autre spin-off du laboratoire fondée en 2014, Novamet SàrL.
Michel Rappaz a reçu de nombreux prix et distinctions, en particulier le prix Mathewson de co-auteur (1994) et auteur (1997) de l’American Mineral, Metals and Materials Society (TMS), le prix de la fondation Koerber avec les Profs Y. Bréchet et M. Asbby (1996), la médaille Sainte-Claire Deville (1996) et la Grande Médaille (2011) de la Société Française des Matériaux (SF2M), le prix Bruce Chalmers de la TMS (2002), le prix Mc Donald Memorial Lecture du Canada (2005), la médaille d’or de la Société Européenne des Matériaux (FEMS, 2013) et le prix Brimacombe de la TMS (2015). Il fait partie des “Highly-Cited Authors” de ISI, il est fellow des sociétés ASM, IOP et TMS, et a écrit plus de 200 publications et deux livres.
Yves Weinand
Biography
Architect and civil engineer, Prof. Dr. Yves Weinand is one of the most recognised researchers in the field of contemporary wood construction. Founder of the Bureau d'Etude Weinand, he has, since 1996, designed and worked on many emblematic wooden buildings, such as the Saint Loup Chapel, the new Vaudois Parliament or, more recently, the Timber Pavilion of Vidy in Lausanne. His fundamental research questions the technical and static possibilities of wooden materials. The interdisciplinary exploration carried out at the EPFL's Laboratory for Timber Constructions (Ibois), of which he is director, concerns wood in all its aspects, from round wood to manufactured wood. The recent research carried out at Ibois on free structures with wood-wood connections (without screw nor glue) has been the subject of several technological transfers, and stands as tangible proof of new possibilities for wood construction. Yves Weinand is currently working on a large-scale project for a hall for the head office of a joinery in Luxembourg, consisting of a succession of arches with spans of 22.5 to 53.7m, entirely assembled in wood ). Through new innovative approaches, the ambition of his research is to develop a new generation of renewable and ecological wooden construction.He is regularly invited to present his work at international symposia on timber construction.
