Model Refinement and Damage Location for Intelligent Structures

Damage identification and health monitoring of structural and mechanical systems from changes in their vibration characteristics: A literature review

“…Reviews of these methods have been published by Smith and Beattie (1991a), Zimmerman and Smith (1992), Hemez (1993), and Kaouk (1993). The problem is generally formulated as a Lagrange multiplier or penalty-based optimization, which can be written as…”

Vibration-Based Model-Dependent Damage (Delamination) Identification and Health Monitoring for Composite Structures — A Review

“…Also, because of their global nature, these techniques allow the customization of measurement points. Another major advantage is that the modal information is cheap to obtain and easy to extract [9].…”

“…According to their di!erent detection techniques, the modal analysis methods can be divided into the following major categories [9,10]: modal shape changes methods [11,12], modal shape curve methods [13,14], sensitivity-based update methods [15,16], eigenstructure assignment methods [17,18], optimal matrix update methods [19,20], changes in measured sti!ness matrix methods [21,22], frequency response function method [23,24], and combined modal parameters method [25].…”

Structural damage detection using the transformation matrix

“…The first part of the problem has led to the development of identification techniques which can adjust structural parameters, such as mass and stiffness matrices, in order to reproduce the measured data of structures [5][6][7][8]. Nevertheless, these procedures could destroy the 0045-7949/$ -see front matter Ó 2004 Elsevier Ltd. All rights reserved.…”
