Abstract:

The aim of this paper is to find the regions of dynamic stability of systems of beams and frames with finite displacements and rotations. A suitable numerical procedure allows regions of dynamic stability to be obtained for any value of the dynamic force, taking into account the different characteristics of constraints, inertia and stiffness. A set of numerical applications is presented to show the capabilities of the proposed numerical method in the frame of the dynamic stability of beams.
