Abstract

This paper proposes a new numerical technique for the free vibration analysis of non-rotating and rotating Timoshenko beams with damaged boundaries. For this purpose, the Chebyshev collocation method is applied to obtain the natural frequencies and mode shapes. The damaged boundaries of the Timoshenko beam are represented by distributed translational and torsional springs. In the present study the boundary conditions are coupled with the governing equation to formulate the eigenvalue problem.
