Free Vibration of Cracked Cantilever Beams: Analytical and Experimental Modelling

Yıl 2018, Cilt: 13 Sayı: 1, 1 - 7, 01.03.2018

Öz

This study presents free
vibration of cantilever beams with multiple cracks. The problem is solved
analytically by the transfer matrix method, and is validated experimentally by
the operational modal analysis. Six damage scenarios are considered to study
crack effect on the natural frequencies and corresponding mode shapes. Graphs
and tables for numerical results are given and discussed. Results show that
crack occurrence in a beam significantly changes its dynamic behavior.
