Dynamic Stability of Monosymmetrical Thin-Walled Structures

A study is made on the dynamic stability of thin-walled beams of monosymmetrical cross section. Under the action of axial periodic loads, the parametric excitation of the coupled flexural-torsional type of vibrations is investigated. The nonlinear differential equations and the appropriate boundary conditions used in the analysis of the problem were obtained using the energy formulation. The effect of large angles of rotation and the effect of …
