Abstract
In this study we investigate the effect of abrupt geometric discontinuities on the vibration of a Timoshenko rotating beam. The beam model is created using finite element code developed on MATLAB. Stop and pass bands are identified using periodic analysis for single cell. The results are verified using published data. Numerical results indicate the effectiveness of such structure configuration on vibration attenuation.
