- Abstract
- Problems related to the stability and behavior of a cantilevered beam with a tip mass on an elastic foundation and
subjected to a distributed follower force are addressed. The stability of a beam partially attached to an elastic foundation
is also considered. The dynamic stability of a beam subjected to a distributed follower force is formulated by using
finite element method to get a general eigenvalue problem. The influence of the modulus on the elastic foundation and
the ratio of the cantilevered beam’s mass to the tip mass on the critical flutter are investigated. Finally, the stability of
the cantilevered beam is found to depend on both the modulus of the elastic foundation and the ratio of the cantilevered
beam’s mass to the tip mass.
