Abstract
To monitor the operating state of a composite structure formed from at least two different materials and subject to a uniform force or load over its entire surface, the deformation at the interface between the two materials is measured. A comparison with a reference quantity of the structure, normally produced by the force applied thereto, indicates the operating state. When the composite structure forms the wall ( ) of a reservoir ( ), monitoring takes place in an instrumentation box ( ) joined to the reservoir. When a critical threshold is exceeded, an alarm indicator ( ) is triggered on the box ( ).
