Damage localization in beams and plates using vibration characteristics
Description
Dynamic computer simulation techniques are used to develop and apply a multicriteria procedure, incorporating changes in natural frequencies, modal flexibility and modal strain energy, for damage localization in beams and plates. Numerically simulated modal data obtained through finite element analyses are used to develop algorithms based on changes of modal flexibility and modal strain energy before and after damage and used as the indices for assessment of the state of structural health. The proposed procedure is illustrated through its application to flexural members like beams and plates under different damage scenarios, and the results confirm its feasibility for damage assessment.
Impact and interest:
Citation counts are sourced monthly from Scopus and Web of Science® citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
