DISPOSITIF DE MESURE DE LA CORROSION DANS UNE STRUCTURE METALLIQUE OU COMPRENANT AU MOINS UNE ARMATURE METALLIQUE, UTILISATIONS ET PROCEDE ASSOCIES |
摘要 |
Device for measuring corrosion in a structure. It comprises: at least one assembly comprising a metallic part (2) intended to be fixed to the structure and able to deform under the effect of corrosion and/or a thermomechanical variation, and transduction means (4) comprising an optical fibre (3) fixed to the metallic part in a prestressed state, the transduction means being able to modify light propagating in the fibre under the effect of a stress applied to the fibre; means for measuring and processing the spectral responses supplied by the transduction means of said at least one assembly. The metallic part is segmented longitudinally in order to form an alternation of segments covered by a corrosion-protection material (8) and uncovered segments, in order to distinguish the thermomechanical influence of the structure from the mechanical effects caused by corrosion. |
