Abstract :

We propose to study and develop a methodology based on a numerical twin in order to estimate the mechanical properties and the lifetime of a composite material in real time. The objective is to predict if a composite part is still operational after an impact and/or a crash or to quantify the level of mechanical performance after the impact.
The methodology used is based on the combination of data from sensors integrated in the product with a numerical simulation model to monitor the health of the material during its life cycle. The combination of measurement and simulation makes it possible to satisfy the hypotheses made by the modeling and to reduce the instrumental cost by limiting it to what is necessary. This digital twin makes it possible to go further in the interpretation of the data and offers a global traceability of the product quality.
This project focuses on the dynamic modeling of composite structures (impact and shock), durability and damage. The work will be initiated at the scale of the test piece, then on a semi-industrial demonstrators from IPC, Industrial Technical Center for Plastic and Composite
