Team presentation

Structural Health Monitoring (SHM) is the whole process of the design, development and implementation of techniques for the detection, localization and estimation of damages, for monitoring the integrity of structures and machines within the aeronautic, civil and mechanical engineering infrastructures.

SHM is now also spreading over most transportation (naval, railway and automobile) infrastructures and vehicles. This calls for new research investigations within the sensor data information processing community. In particular, efficient and robust methods for structural analysis, non destructive evaluation, integrity monitoring, damage diagnostics and localization, are necessary for fatigue and aging prevention, and for condition-based maintenance.

In this context, and based on our background on model-based statistical methods, our objectives are the incorporation of additional model-based knowledge about the physics (thermodynamics, aerodynamics) within statistical inference tools (identification, detection, rejection), and the investigation of the complexity, efficiency and robustness of the resulting algorithms.
