“…Nayak et al 14 analysed the buckling strength of a sandwich beam with viscoelastic end support and observed that the end flexibilities improved the stability. Pradhan and Dash 15 considered viscoelastic end support with a tapered sandwich beam and analysed the impact of the end flexibilities on the beam’s dynamic stability. Pratiher and Dwivedy 16 investigated the frequency response and non-linear vibrational characteristics of a magnetoelastic beam with one end fixed and the other end attached with a tip mass.…”

This study investigated the parametric instability of a single elastic beam with spring attachment on the top and viscoelastic springs as end supports. The beam considered is pre-twisted with a pin connection at both ends that supports the beam. The analytical solution of the problem is expressed in the matrix form achieved from the implementation of Hamilton’s principle and General Galerkin’s method, from which both static and dynamic stability of the beam can be investigated. The results of various influential dimensionless parameters such as stiffness, mass, length, position of the spring attachment, and stiffness of the viscoelastic springs on both the stabilities are studied. This analysis concluded that the spring attachment on the system leads to substantial contribution in improving the stability. The viscoelastic springs also contribute in upsurging the beam’s stability. Three different profiles of the beam have been considered, and for each profile, three different types of springs have been examined. The results revealed that the beam with parabolic profile and stiffness of the spring attachment with parabolic variation is most effective towards strength-to-weight ratio.
