Historically, work on this theme began with the stamping of metal parts and the manufacturing processes for fiber-matrix composite structures. The objective of this theme is to develop tools and methods for the optimal design of products by integrating business rules. Its originality lies in understanding, mastering, and then optimizing the relationship between the product, its constituent materials, and the manufacturing process in order to achieve the desired functionality. Depending on the degree of control over the product's production, the research objectives may be either to optimize the process control parameters to obtain the best possible product, or to select the manufacturing process and materials to obtain an initial series of products that meet the requirements, and then move on to a phase of optimizing the manufacturing process.
Scientific challenges and obstacles
Our approach is based on modeling complex systems (materials, products, or processes) at different stages of understanding the phenomena involved. The central element of this process is the validity of the experimental input data. It is essential to ensure that the experimental data required to build, evaluate, and test the model are available and reliable. Research in this area 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 process prediction models studied in order to estimate their impact on the final mechanical state of the part;
- The establishment of methods for selecting material/process combinations that enable the production of functional parts that meet the specified requirements;
- The design of specific characterization and testing methods at the material, product, or process level to provide reliable data for the models developed.
