Dynamic stability of elastic structures: a finite element approach
In this paper the finite element method is used to find the regions of dynamic stability of beams and frames. A suitable numerical procedure allows diagrams to be obtained where these regions are located as functions of the dynamic force applied and vibration frequency of the structures analyzed, taking into account the different characteristics of constraints, inertia and stiffness. A set of numerical applications concerning beams and framed structures is presented.
