TL;DR: A genetic algorithm is applied to the problem of damage detection using vibration data to identify the position of one or more damage sites in a structure and to estimate the extent of the damage at these sites.

TL;DR: The IRS method is extended by obtaining the equivalent transformation based on dynamic rather than static reduction, and an iterative algorithm, based on the IRS method, is described, which provides a reduced model which reproduces a subset of the modal model of the full system.

TL;DR: There are a number of approaches to the modeling of cracks in beam structures reported in the literature, that fall into three main categories; local stiffness reduction, discrete spring models, and an... as mentioned in this paper.

TL;DR: In this paper, the problem of choosing an optimum set of measurement locations for experimental modal testing and suggesting criteria whereby the suitability of the chosen locations can be assessed is examined.

TL;DR: This paper examines the problem of choosing an optimum set of measurement locations for experimental modal testing and suggests criteria whereby the suitability of the chosen locations can be assessed and suggests methods of coordinate selection based on Guyan reduction and the Fisher information matrix.
