Synpopsis Dynamic Stability of Thin-walled Bars with Open Section by Professor Dr. Ing. N. D. Popescu
In this paper is presented a study on dynamic stability of thin-walled bars with open cross-section, subjected to compression by an axial force, composed from a static component and a variable one. The case of non-symmetric profiles is analysed in the first instance, to obtain general equations of vibratory motions; these are then particularized for profiles with an axis of symmetry, currently used in construction.
