This paper presents a novel damage localization approach for active ultrasonic structural health monitoring. The formalism considers triplets of two actuators and one sensor in a spatially distributed transducer network. Depending on time-of-flight measurements that are automatically conducted on differential signals, the defect position in isotropic and quasi-isotropic plates is located very rapidly without the wave velocity information. This is particularly beneficial when the wave speed… CONTINUE READING
