... method developed was applied to two different structural health monitoring investigations, one involving loss-of-material and the other involving loss-of-fluid. The loss-of-material scenario simulated the process of external pipe wall corrosion, and the developed method was able to detect material loss...

... the present adoption of bifurcations for structural health monitoring applications. However, a notable distinction between micro- and macro-scale structures makes direct implementation of bifurcations for structural sensing a challenge: the existence of strong nonlinearity. Nonlinear responses...

...Eloi Figueiredo; Gyuhae Park; Kevin M. Farinholt; Charles R. Farrar; Jung-Ryul Lee In this paper, time domain data from piezoelectric active-sensing techniques is utilized for structural health monitoring (SHM) applications. Piezoelectric transducers have been increasingly used in SHM because...

...Colin C. Olson; M. D. Todd; Keith Worden; Charles Farrar Active excitation is an emerging area of study within the field of structural health monitoring whereby prescribed inputs are used to excite the structure so that damage-sensitive features may be extracted from the structural response...

... for the discrepancies between the ideal bonding hypothesis and the actual shear-lag load transfer mechanism. The paper further shows that the capability to excite only one desired Lamb wave mode is critical for practical structural health monitoring (SHM) applications such as PWAS phased array technique (e.g...
