Strategies for guided-wave structural health monitoring
TL;DR: It is shown that the number of sensors required per unit area to reliably detect a prescribed type of damage is prohibitively high, even in the presence of modest temperature fluctuations, hence some form of temperature compensation is absolutely essential for guided-wave SHM systems to be viable.
Journal ArticleDOI
Efficient temperature compensation strategies for guided wave structural health monitoring
TL;DR: In this paper, the authors quantitatively describe two different methods to compensate for the temperature effect, namely optimal baseline selection (OBS) and baseline signal stretch (BSS), and investigate the effect of temperature separation between baseline time traces in OBS and the parameters used in the BSS method.
Journal ArticleDOI
Chirp excitation of ultrasonic guided waves
TL;DR: Broadband and narrowband chirp excitations are utilized to address the need to both test at multiple frequencies and achieve a high signal-to-noise ratio to minimize acquisition time.
Journal ArticleDOI
The use of non-collinear mixing for nonlinear ultrasonic detection of plasticity and fatigue.
TL;DR: Measurements made on a sample after plastic deformation and on a samples subjected to low-cycle fatigue show that the non-collinear technique is indeed capable of measuring changes in both, and is therefore a viable inspection technique for these types of material degradation.
Journal ArticleDOI
Evaluation of the damage detection capability of a sparse-array guided-wave SHM system applied to a complex structure under varying thermal conditions
TL;DR: A sparse-array structural health monitoring (SHM) system based on guided waves was applied to the door of a commercial shipping container, and comparison of signals transmitted between different transducer pairs before and after damage was used to give an initial indication of defect detectability.
