Abstract

This paper peresents the 2–D DISCRETE WAVELET–based CRACK DETECTION using STATIC AND DYNAMIC RESPONSES in PLATE STRUCTUREs. Over the last few decades, the wavelet–based techniques of damage identification methods have been presented and developed in civil and mechanical structures. The techniques are based on a comparison between the current structural responses as damaged structure and those of the previous baseline state, which is considered to be the health structure. To impliment the damage detection of PLATE STRUCTUREs, in this study the displacement, rotation and stress as the static responses and the mode shapes as the dynamic responses are considered in the CRACK DETECTION procedure. The numerical results show that the wavelet–based CRACK DETECTION is sensitive to number of cracks in PLATE STRUCTURE. In other words, the existence of a crack can be potentially identified using each of the static or dynamic responses of PLATE STRUCTUREs. Moreover, if multi–cracks exists in PLATE STRUCTURE, both STATIC AND DYNAMIC RESPONSES of PLATE STRUCTURE should be utilized in the damage detection procedure.
