Damage identification in beams and plate using curvature mode shape and its has become a research focus of increasing interest during the last few years. Hence this paper presents the numerical and experimental studies for damage detection in beam and plate structure with mode shape curvatures. The purpose of the study is to present the influence of the higher order modes of the beams and plates on damage detection and quantification and location. We observed that detection quality for particular mode shape depends on order of mode shape and it is also demonstrated that the location and quantification of single and multi cracks can be detected by this method. First, the displacement mode shapes obtained from the intact and damaged beams which are converted into mode shape curvatures. In this the first five modes of cantilever beam are considered and the influence of the mode order of beam and plate on the effectiveness of damage detection by the vibrational setup.
