Abstract
The present invention relates to a method of sensing permanent deformation of a structure, the method comprising the steps of; determining the strain required to permanently deform a structure; securing to the structure one or more strain sensors so that a strain sensor will deform when the structure is deformed, wherein the or each strain sensor comprises one or more optical fibers and wherein the or each strain sensor is configured such that it will permanently deform only when the structure permanently deforms; carrying out distributed fiber optic analysis to sense if a strain sensor has been permanently deformed, wherein a permanent deformation of a strain sensor indicates permanent deformation of the structure. The present invention also relates to a corresponding assembly.
