| Abstract: | The purpose of the present paper is to show that the
problem of geometrically non linear free vibration of
symmetrically and asymmetrically laminated composite beams
with immovable ends can be reduced to that of isotropic
homogeneous beams with effective bending stiffness and axial
stiffness parameters. This simple formulation is developed using
the governing axial equation of the beam in which the axial
inertia and damping are ignored. The theoretical model is based
on Hamilton’s principle and spectral analysis. A simplified
multimode approach, based on the explicit formulation
developed previously for various nonlinear vibration problems, is
derived, leading to a multimode explicit description, to calculate
the fundamental nonlinear frequency parameters which are
found to be in a good agreement with the published results. The
non-dimensional curvatures associated to the fundamental mode
are also given in the case of clamped-clamped symmetrically and
asymmetrically laminated composite beams. |
