Damage detection in a free-free beam structure using reconstructed mode shape data: Numerical approach

The purpose of this work is to localise and magnify the effects of cracks from numerically computed cracked beam mode shapes using reconstructed mode shape data. In general, detecting the presence of a crack solely by observing the vibration mode shape data is difficult. The mode shape data, which...
