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
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

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
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 ...
Damage detection in uncertain nonlinear systems based on stochastic Volterra series
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, ...
On the Frequencies for Structural Health Monitoring in Plates with Symmetrical Damage: An Analytical Approach
The damage detection process in structures has been an important challenge for the engineering community. The design of structural health monitoring (SHM) systems usually involves selection of actuators and sensors, their ...
Impedance-based damage detection under noise and vibration effects
The electro-mechanical impedance technique has been extensively studied in recent decades as a non-destructive method for detecting structural damage in structural health monitoring applications using low-cost piezoelectric ...
