We are happy to invite you to come back in Poitiers for this 20th edition either as presenter or participant. This edition will be held for the first time in both physical and distance modes. We promise this year a very special edition with a great Gala on October 7 for the occasion of the 20th edition but also for Michel’s last workshop before retirement! This workshop is primarily intended to provide an opportunity for researchers and practitioners from Industry and Academia to gather and share their knowledge regarding high performance materials for sliding bearings. The conferences shall offer to the participants the opportunity to study the latest contributions on this subject and to identify the problems met by industrials by favouring a common approach. This event is organized by the Mechanical Engineering and Complex Systems department of the Pprime Institute (UPR 3346, CNRS-Université de Poitiers-ISAE-ENSMA). Furthermore, the workshop is organized under the auspices of the French section of the ASME and of AFM.
