False alarms in damage detection approaches
Structural Health Monitoring (SHM) denotes a system with the ability to detect and interpret adverse changes in structures in order to improve reliability and reduce life-cycle costs. The greatest challenge for designing ...
Ensemble classification method for structural damage assessment under varying temperature
(SAGE Publications Ltd, 2017)
Vibration-based damage assessment approaches use modal parameters, such as frequency response functions, mode shapes, and natural frequencies, as indicators of structural damage. Nevertheless, these parameters are sensitive ...
Fabrication of a novel biosensor for biosensing of bisphenol A and detection of its damage to DNA
(Elsevier Science, 2019-04)
In this work, a novel electrochemical biosensor has been fabricated based on step-by-step modification of aglassy carbon electrode (GCE) with methylene blue (MB)-DNA/multiwalled carbon nanotubes (MWCNTs)-chitosan (CS)/palladium ...
Fuzzy clustering and AR models for damage detection in CFRP coupons considering loading effect
This paper proposes a strategy to avoid false alarms by distinguishing operation effects from damages effects in composite laminates. This strategy is based on active and sensing piezoelectric patches receiving Lamb waves ...
Improvement of damage-assessment results using high-spatial density measurements
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2005-06)
Model-based damage assessment is based on measuring the distance between experimental and analytical results. In practice, measurements yield only partial mode shapes with respect to the total degrees of freedom present ...
Structural health monitoring in a buckled beam using Volterra series
This paper proposes a new method to detect damages in structures vibrating with nonlinear behavior. The approach proposed is based on Volterra series and can separate the linear and nonlinear contributions of the responses. ...
