Timoshenko beam under Winkler foundation
Conférence : Communications avec actes dans un congrès international
We are interested in buckling for Timoshenko beam supported along its length by an elastic wall (Winkler
foundation) and subjected to a longitudinal force. We use analytical methods to determine buckling load
and mode shape rather than numerical methods. Haringx and Engesser models are compared. We show
that the rigidity of the wall solely gouverns the phenomena and that the two models are equivalent whatever
the parameters of the problem.
