In view of an extensive literature about guided waves propagation, interaction and numerical simulation in platelikeudstructures made of metallic and composite materials, a lack of information is pointed out regarding their reliability inudstructural health monitoring approaches. Typically, because of uncertainties in the inspection process, the capability of nondestructiveudtesting systems is expressed by means of suitable probability of detection curves. Based on Berens’ model, a linearudrelationship is established between probability of detection and flaw size. Although the uncertain factors differ from a nondestructiveudinspection technique and a structural health monitoring approach, the same mathematical framework can beudassumed. Hence, the authors investigated the application of a recently developed non-destructive testing Multi-Parameter PODudapproach to a guided waves based SHM one: numerical simulations as well as experimental data from flawed plates wereudcombined to bring about a “master” POD curve. Once established, it can be used to build the POD curves of the single keyudfactors as flaw size, orientation, structural attenuation and so on.
