First, governing equations for antiresonant frequency are conducted and used for both computing antiresonant frequencies versus crack parameters and measuring-loading colocation and identifying cracks by measured antiresonant frequencies. Then, a procedure is proposed for crack identification in cantilever beam by antiresonant frequencies based on the so-called crack scanning method. Theoretical development is illustrated by numerical examples.</p>}, number={4}, journal={Vietnam Journal of Mechanics}, author={Khiem, Nguyen Tien and Tuan, Nguyen Minh and Lien, Pham Thi Ba}, year={2021}, month={Dec.}, pages={389–405} }
