A Spectral Approach For Damage Quantification In Stochastic Dynamic Systems
(Academic Press Ltd- Elsevier Science LtdLondon, 2017)
Damage detection in an uncertain nonlinear beam
(2017-01-01)
The present paper proposes the use of discrete time Volterra series expanded with Kautz filters for predicting the experimental response of a nonlinear beam, taking into account uncertainties that are inherent to the system. ...
Structural Health Monitoring Using Time Reversal And Cracked Rod Spectral Element
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTDLONDON, 2016)
Analysis of wave scattering from non-symmetric discontinuities in one-dimensional wave-guides
(2017-01-01)
Predicting the scattering from waves that are incident on a damaged section of structure is of importance in structural health monitoring and nondestructive testing techniques to detect dam-age. High frequency waves are ...
Damage Quantification in Composite Structures Using Autoregressive Models
(2020-01-01)
When small damage is detected in its initial stage in a real structure, it is necessary to decide if the user must repair immediately or keep on safely monitoring it. Regarding the second choice, the present paper proposes ...
Lamb wave inspection using piezoelectric diaphragms: An initial feasibility study
(2021-11-01)
Lamb wave-based inspection has been extensively investigated and reported in the literature as a non-destructive technique in structural health monitoring and other applications. The generation and reception of Lamb waves ...
Damage Detection Approach for Bridges under Temperature Effects using Gaussian Process Regression Trained with Hybrid Data
(Asce-amer Soc Civil Engineers, 2022-11-01)
The success of detecting damage robustly relies on the availability of long periods of past data covering multiple weather scenarios and on the information contained in the data used during the learning process. Thus, the ...
A prognostics approach based on the evolution of damage precursors using dynamic Bayesian networks
(SAGE, 2016)
During the lifetime of a component, microstructural changes emerge at its material level and evolve through time.
Classical empirical degradation models (e.g. Paris Law in fatigue crack growth) are usually established ...
Technique to combine images produced by different propagation modes of guided waves for damage detection and contrast improvement in plate-like structures
(2012-12-01)
This paper describes an image compounding technique based on the use of different apodization functions, the evaluation of the signals phases and information from the interaction of different propagation modes of Lamb waves ...
