Bas\u00e9e sur une technologie brevet\u00e9e d’\u00e9tude statistique de la rugosit\u00e9 des faci\u00e8s de rupture, la m\u00e9thode d\u00e9velopp\u00e9e par Tortoise et int\u00e9gr\u00e9e par le Cetim dans son offre, fonctionne \u00e0 partir de l\u2019analyse d’un petit fragment d\u2019un mat\u00e9riau rompu.

Le Centre Technique des Industries M\u00e9caniques (CETIM) a int\u00e9gr\u00e9 l\u2019outil original d\u2019analyse de d\u00e9faillance mis au point par la start-up francilienne Tortoise. Cette solution, adapt\u00e9e sur mesure aux besoins sp\u00e9cifiques des diff\u00e9rents domaines industriels, compl\u00e8te l’accompagnement pluridisciplinaire propos\u00e9 par le Cetim dans ce domaine. Tortoise a \u00e9t\u00e9 fond\u00e9e en 2017 par Laurent Ponson, charg\u00e9 de recherche \u00e0 l\u2019Institut Jean le Rond d\u2019Alembert, pour mettre en \u0153uvre de fa\u00e7on pratique le fruit de ses recherches. La start-up d\u00e9veloppe et commercialise ainsi une solution innovante baptis\u00e9e “fractographie statistique”. Bas\u00e9e sur une technologie brevet\u00e9e d’\u00e9tude statistique de la rugosit\u00e9 des faci\u00e8s de rupture, cette m\u00e9thode fonctionne \u00e0 partir de l\u2019analyse d’un petit fragment d\u2019un mat\u00e9riau rompu (d\u00e8s 1\u202fmm\u00b2). Elle est capable ainsi de d\u00e9terminer ses propri\u00e9t\u00e9s m\u00e9caniques, comme sa t\u00e9nacit\u00e9 ou sa contrainte \u00e0 la rupture, et de remonter au niveau de chargement m\u00e9canique atteint en service. Cette donn\u00e9e permet d\u2019identifier au plus pr\u00e8s les causes de la d\u00e9faillance puis d\u2019\u00e9laborer un mod\u00e8le m\u00e9canique ciblant les corrections \u00e0 apporter pour rendre le syst\u00e8me plus fiable et durable, ou pr\u00e9disant la dur\u00e9e de vie r\u00e9siduelle d\u2019une structure jumelle en exploitation. Une condition sine qua non pour se pr\u00e9munir de futures avaries. Applicable \u00e0 tous les mat\u00e9riaux, du m\u00e9tal au verre en passant par la c\u00e9ramique et les polym\u00e8res, cette m\u00e9thode est utilis\u00e9e d\u00e8s la phase de conception pour am\u00e9liorer les composants m\u00e9caniques ou en d\u00e9velopper de nouveaux. Le partenariat avec le Cetim se traduit concr\u00e8tement par l\u2019interfa\u00e7age de ces nouvelles donn\u00e9es avec les services propos\u00e9s par ce dernier. Dans un premier temps, un scan du faci\u00e8s de rupture est ainsi r\u00e9alis\u00e9 via un profilom\u00e8tre. Les donn\u00e9es recueillies font alors l\u2019objet d\u2019un traitement statistique par les algorithmes mis au point par Tortoise. Les r\u00e9sultats sont ensuite analys\u00e9s de fa\u00e7on d\u00e9taill\u00e9e et affin\u00e9s par les experts de Tortoise et du Cetim \u00e0 la lumi\u00e8re de l\u2019ensemble des investigations men\u00e9es, afin de converger vers un diagnostic consolid\u00e9. On peut ainsi engager des d\u00e9marches de r\u00e9solution de probl\u00e8mes, comme l\u2019assistance \u00e0 la reconception par le Cetim.<\/p>\n\n\n\n
