A method is developed for the detection of the existence and location of structural damage. Structural damage is considered to be at the macroscopic level. The detection is carried out in two parts. In the first part, the eigensolution of the structure is identified using a modal parameter identific
This paper deals with the identification of a single defect in a discrete spring-mass or beam-like system by measurements of damage-induced shifts in resonance frequencies and antiresonance frequencies. For initially uniform discrete systems, it is shown how the measurement of an appropriate set of
A non-destructive time domain approach to examine structural damage is presented. Unlike frequency domain methods which generally rely on analytical models, this method is independent of modal parameters and analytical models. Time histories of the vibration response of the structure were used to id
