On the large postbuckling response of nonconservative continuous systems (Q1199315)

The large postbuckling response of a uniform cantilever beam subjected to a partial follower compressive load of constant magnitude is presented. The range of values of the nonconservativeness loading parameter for which a divergence instability occurs is theoretically established. The boundary between divergence and flutter instability corresponds to a double critical point where the first and second buckling loads (eigenvalues) coincide. It was also theoretically established that the critical points corresponding to these loads are stable symmetric.
