Some Observations on Two Theorems in the Theory of Stability of Non-Conservative Elastic Systems.

Abstract

The analytical conditions for which the critical loads of flutter and divergence of an undamped, non-gyroscopic elastic system of two degrees of freedom subjected to circulatory forces are equal are derived. These theoretical results are applied to a non-conservatively loaded double pendulum having elastic hinges and an elastic support at its free end. Numerical values of the support stiffness parameter, the force orientation parameter, and the equal critical flutter and divergence loads are reported.
