Le laboratoire Procédés et Ingénierie en Mécanique et Matériaux (PIMM) rassemble une vaste gamme de spécialistes allant de la mécanique des matériaux et des structures à la chimie des polymères, des procédés de mise en forme et d’assemblage aux méthodes avancées de la simulation numérique. Les recherches sur les procédés laser et les procédés de mise en forme des polymères s’appuient sur un vaste ensemble de moyens expérimentaux.
Les travaux s’attachent en particulier aux conséquences des procédés sur les propriétés d’emploi, via les défauts et les modifications de microstructures engendrées. Les activités développées en dynamique des structures et en commande et surveillance des systèmes, au-delà de leur justification propre, permettent d’apporter de nombreuses contributions à la compréhension et à la simulation des procédés. Nous pouvons ajouter que le laboratoire possède une compétence bien établie dans le domaine de la durabilité des matériaux, notamment pour les matériaux plastiques. Enfin, depuis très récemment, nous développons des méthodes de Data Driven pour enrichir nos analyses et nos modèles dans nos diverses activités de recherche.
The Process and Engineering in Mechanics and Materials laboratory (PIMM) brings together a wide range of specialists from the mechanics of materials and structures to the polymer chemistry and from forming and assembling processes, to advanced methods for numerical simulation. Research on laser processes and procedures forming polymers are based on an extensive set of experimental means.
In particular, we deal with the consequences of the processes on the service properties via the induced defects and microstructural modifications. The activities in structural dynamics, system and vibration control, beyond their own justification, can make significant contributions to understand and simulate processes. We can add that the laboratory has a well-established expertise in the field of aging of polymer structures in service conditions. At last, we developed Data Driven approaches to improve the analyses and our modeling of our various scientific fields.
