“…To examine the transverse vibrations of a 1D beam structure, the Timoshenko beam model has been widely adopted to take into account the effects of shear deformation and rotatory inertia on the dynamic responses. In transverse vibration analysis, various solution techniques have been described in the literature including MAM or eigenfunction expansion methods [1,2], mode summation methods or assumed mode methods [3][4][5], semianalytical methods [6][7][8][9][10][11], integral transform methods (Laplace-Carson transform and Fourier transform) [12][13][14], transfer matrix method [15], Lagrange multiplier methods [16,17], Galerkin methods [18,19], finite element methods [20,21], finite difference method [22], time-domain spectral element method [23], and frequency-domain spectral element method [24].…”
