Title

On The Stabilization Of Nonstationary Parametric Main Resonance Of A Laminated Angle-Ply Column

Abstract

The main resonance of a laminated angle-ply column subjected to nonstationary parametric excitations is studied using the asymptotic method. The nonstationary processes used are either linear or cyclic excitation frequency, i.e. Ω(t) = Ω0 + βt or Ω(t) = Ω0 + μ sin βt. The study includes the effects of geometrical nonlinearities, initial conditions and various sweep rates β. Effective and fast stabilization is observed. This is significant from the design and basic point of view. Separatrices (defined in the text) are also obtained for various sweep rates in the linear excitation frequency.
