Historically, the theme's work has focused on the stamping of metal parts and manufacturing processes for fiber-matrix composite structures. The aim of this theme is to develop tools and methods for optimal product design, integrating business rules. Its originality lies in understanding, mastering and then optimizing the relationship between the product, its constituent materials and the implementation process to achieve the desired functionality. Depending on the degree of mastery of the product's production, the research objectives may be either to optimize process control parameters to obtain the best possible product, or to select the manufacturing process and materials to obtain an initial series of products meeting the need, and then move on to a manufacturing process optimization phase.
Scientific issues and challenges
Our approach is based on modeling complex systems (materials, products or processes) at different stages of understanding the phenomena involved. Central to this process is the validity of the experimental input data. We need to ensure that the experimental data required for model construction, evaluation and testing are available and reliable. The theme's research work focuses on :
- The development of material behavior models including levels of uncertainty to guarantee the performance of the process and/or product model;
- Building links between different modeling scales (Micro, Meso and Macro)
- The implementation of predictive models for the processes to estimate their impact on the final mechanical state of the part;
- The establishment of selection methods for material/process combinations to produce functional parts that meet expressed needs;
- The design of specific characterization and testing methods at material, product or process scale to provide reliable data for the models developed.
