This study is concerned with the free bending vibrations of two rectangular, orthotropic
plates connected by an adhesively bonded lap joint. The influence of shear deformation and
rotatory inertia in plates are taken into account in the equations according to the Mindlin
plate theory. The effects of both thickness and shear deformations in the thin adhesive layer
are included in the formulation. Plates are assumed to have simply supported boundary
conditions at two opposite edges. However, any boundary conditions can be prescribed at …

Free vibrations of adhesively bonded orthotropic plates is studied. Mindlin's plate theory is
used to take into account shear deformation and rotatory inertia. Both effects of thickness
and shear deformation in the adhesive layer is included. Plates are assumed to have simply
supported boundary conditions on two opposite edges, However, combinations of any
boundary conditions can be prescribed on other edges. For the case of special orthotropy in
which principal directions of material are parallel to the sides of the plates, a revised form of …
