« la Pérouse » Award winner – 2020 edition
On September 4, 2020, Cédric Leblond, head of scientific calculations/simulation, and Emilien Billaudeau, head of technology, were awarded a distinction for their project, the idea of which was to combine the digital twin of a structure with in situ instrumentation, in order to establish reliable, complete and predictive monitoring.
Their project was a answer to the problem of classical monitoring of structures using data from sensors attached to the structure or in situ. Indeed, the instrumentation cannot cover the whole structure and the most critical areas.
The measurement uncertainties can then strongly reduce the accuracy of the readings and complicate their interpretation. The data generated are therefore incomplete and not perfectly representative of reality.
In this context, relying only on in situ surveys to monitor structures may seem risky, so a progression on the theoretical aspects was necessary as well as the acceleration of the rise in maturity of the technology.
