abstract = {This paper proposes a new damage index named degree of health (DoH) to efficiently tackle
structural damage monitoring in real-time. As a key contribution, the proposed index relies on a
pattern matching methodology that measures the time-of-flight mismatch of sequential ultrasonic
guided-wave measurements using fuzzy logic fundamentals. The ultrasonic signals are generated
using the transmission beamforming technique with a phased-array of piezoelectric transducers.
The acquisition is carried out by two phased-arrays to compare the influence of pulse-echo and
pitch-catch modes in the damage assessment. The proposed monitoring approach is illustrated in a
fatigue test of an aluminum sheet with an initial notch. As an additional novelty, the proposed pattern
matching methodology uses the data stemming from the transmission beamforming technique for
structural health monitoring. The results demonstrate the efficiency and robustness of the proposed
framework in providing a qualitative and quantitative assessment for fatigue crack damage.},
