Abstract : For several years the research team S4M focuses on a technological approach to SHM with the aim for monitoring of complex systems by intelligent sensors distributed: Smart Sensing. The S4M team led instrumentation complex structures work through the deployment of distributed monitoring systems and search for markers of aging by measuring and operating signals through deployed MEMS sensors. Different areas have already been addressed with the work conducted jointly with aircraft manufacturers. This research, conducted in partnership with the LMDC-INSA laboratory focuses on the concrete like material reinforced composite plates as heterogeneous structure requiring periodic or continuous monitoring. One of the challenges is to control preventive maintenance or oversizing trusted coefficients by providing a non-destructive testing method. Our research goal is to help in the search for a signature in the signals measured by piezo sensors in response to pulses generating propagation of mechanical waves reflecting an aging or damage to the beam structure of reinforced concrete.
