Damage identification in bars with a wave propagation approach: performance comparison of five hybrid optimization methods
(2013)
The formulation and solution of the inverse problem of damage identification based on an one-dimensional wave propagation approach are presented in this paper. Time history responses, obtained from pulse-echo synthetic ...
Detection of structural damage and estimation of reliability using a multidimensional monitoring approach
(SAGE PUBLICATIONS LTD, 2018-04-01)
Many structural elements are exposed to load conditions that are difficult to model during the design phase, such as environmental uncertainties, random impacts, and overloading, amongst others, thus increasing unprogrammed ...
Implementation of a Piezo-diagnostics Approach for Damage Detection Based on PCA in a Linux-Based Embedded Platform
(MDPI, 2018-11)
The implementation of damage-detection methods for continuously assessing structural
integrity entails systems with attractive features such as storage capabilities, memory capacity,
computational complexity and ...
Evaluation of the coupled effect of strain localization and asymmetric damage distribution on rope response: numerical approach based on a nonlinear cable-beam element
(Elsevier, 2020)
In this paper, a numerical model to evaluate the impact of the presence of fractured rope components on the static response of ropes is presented. Specifically, the proposed model couples the effects of two phenomena that ...
Adaptive filter feature identification for structural health monitoring in an aeronautical panel
(Sage Publications Ltd, 2014)
Real-Time Structural Damage Assessment Using Artificial Neural Networks and Antiresonant Frequencies
(Hindawi, 2014)
The main problem in damage assessment is the determination of how to ascertain the presence, location, and severity of structural
damage given the structure’s dynamic characteristics. The most successful applications of ...
An Anisotropic Model of Damage and Unilateral Effect for Brittle Materials
(World Acad Sci, Eng & Tech-waset, 2007-01-01)
This work deals with the initial applications and formulation of an aniscitropic plastic-damage constitutive model proposed for non-linear analysis of reinforced concrete structures submitted to a loading with change of ...
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 ...
