The equations of motion of a pre-twisted cantilever beam with a spinning base subject to axial base excitations are formulated by using Euler beam theory and the assumed mode method. The effects of sinusoidal perturbations in terms of the axial accelerations of the beam are then examined by using Bo

This paper deals with the parametric instability of a pre-twisted, cantilevered, three-layered symmetric sandwich beam subjected to a periodic axial load at the free end. The non-dimensional governing equations of motion and the associated boundary conditions are derived by Hamilton's principle. The

The equations of motion of a spinning beam of uniform rectangular cross-section are formulated by using Euler beam theory and the assumed mode method. The equations of motion are then transformed to the standard form of an eigenvalue problem for determining the critical spinning speeds corresponding
