An hybrid real genetic algorithm to detect structural damage using modal properties
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2011-07)
An hybrid real-coded Genetic Algorithm with damage penalization is implemented to locate and quantify structural damage. Genetic Algorithms provide a powerful tool to solved optimization problems. With an appropriate ...
On the application of discrete-time Volterra series for the damage detection problem in initially nonlinear systems
(2017-01-01)
Nonlinearities in the dynamical behavior of mechanical systems can degrade the performance of damage detection features based on a linearity assumption. In this article, a discrete Volterra model is used to monitor the ...
Structural Health Monitoring in Smart Structures Through Time Series Analysis
(Sage Publications LtdLondonInglaterra, 2008)
False alarms in damage detection approaches
(2008-12-01)
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 ...
Damage detection in beams by using artificial neural networks and dynamical parameters
(IMPRENTA UNIV ANTIOQUIAMEDELLIN, 2012-06)
In this paper is presented a multilayer perceptron neural network combined with the Nelder-Mead Simplex method to detect damage in multiple support beams. The input parameters are based on natural frequencies and modal ...
Damage detection in an uncertain nonlinear beam based on stochastic Volterra series: An experimental application
(2019-08-01)
The damage detection problem becomes a more difficult task when the intrinsically nonlinear behavior of the structures and the natural data variation are considered in the analysis because both phenomena can be confused ...
On the use of parallel full-order state observers for damage detection in mechanical systems
(2021-12-01)
According to the literature, structural health monitoring techniques based on state observers usually evaluate the differences between measured and estimated states to detect a damage. The practical application of this ...
Damage detection in uncertain nonlinear systems based on stochastic Volterra series
(2018-01-01)
The damage detection problem in mechanical systems, using vibration measurements, is commonly called Structural Health Monitoring (SHM). Many tools are able to detect damages by changes in the vibration pattern, mainly, ...
Experimental damage detection using system norms
(2006-12-01)
Nowadays there is great interest in structural damage detection in systems using nondestructive tests. Once the failure is detected, as for instance a crack, it is possible to take providences. There are several different ...
