Abstract:A solution is presented, for the non-linear Marguerre dynamic equilibrium and compatability equations, for the large amplitude free flexural vibrations of an imperfect, cross-ply, laminated plate, having elastically restrained edges and resting on an elastic foundation. The analysis is used to study the effects of edge restraints and elastic foundation constants on the frequency ratios of isotropic and CFRP plates. Numerical results are presented graphically.
