DAMPING: A SENSITIVE STRUCTURAL PROPERTY FOR DAMAGE DETECTION

DAMPING: A SENSITIVE STRUCTURAL PROPERTY FOR DAMAGE DETECTION

Data from vibration measurements opens a way to damage assessment by correlatingchanges in system dynamic parameters with damage indicators. Most methods proposed in theliterature are based on the measurement of natural frequencies or modal shapes and modelling damageas local reduction in structural stiffness. In some particular applications these methods, however, haveseveral practical limitations on account of their low sensitivity to damage. This paper shows thatdamping can be used as a ...
