This paper gives an overview of the use of inverse methods in damage detection and
location, using measured vibration data. Inverse problems require the use of a model and …

Structural health monitoring and assessment (SHMA) is exceptionally essential for
preserving and sustaining any mechanical structure's service life. A successful assessment …

A new simplified approach to modelling cracks in beams undergoing transverse vibration is
presented. The modelling approach uses Euler–Bernoulli beam elements with small …

The problem of estimating the optimal sensor locations for parameter estimation in structural
dynamics is re-visited. The effect of spatially correlated prediction errors on the optimal …

Genetic algorithms have been the subject of considerable interest in recent years, since they
appear to provide a robust search procedure for solving difficult problems. Due to the way …

Model updating methods based on structural vibration data have being rapidly developed
and applied to detect structural damage in civil engineering. But uncertainties existing in the …

Damage detection in vibrating beams, or beam systems, is dealt with in this paper. Damage
is represented by a more or less concentrated decrease in stiffness. A linear behavior is …

A statistical method with combined uncertain frequency and mode shape data for structural
damage identification is proposed. By comparing the measured vibration data before …

We define a notion of subspace angles between two linear, autoregressive moving average,
single-input–single-output models by considering the principal angles between subspaces …

This paper addresses the problem of identifying structural damage affecting one zone of a
beam using measured frequencies. The beam model has a zone in which the stiffness is …
