This study is concerned with the free bending vibrations of two rectangular orthotropic places 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 the other two edges. First, equations of motion at the overlap region are derived. Then, a Levy-type solution for displacements and stress resultants are used to formulate the problem in terms of a system of first order ordinary differential equations. A revised version of the Transfer Matrix Method together with the boundary and continuity conditions are used to obtain the frequency equation of the system. The natural frequencies and corresponding mode shapes are obtained for identical and dissimilar adherends with different boundary conditions. The effects of some parameters on the natural frequencies are studied and plotted.

"Free Flexural Vibrations Response of Composite Mindlin Plates or Panels with a Centrally Bonded Symmetric Double Lap Joint (or Symmetric Double Doubler Joint)" Yuceoglu, U.; Guvendik, O.; Ozerciyes, V. (2005-11-11) The present study is concerned with the "Free Flexural Vibrations Response of Composite Mindlin Plates or Panels with a Centrally Bonded Symmetric Double Lap Joint (or Symmetric Double Doubler Joint). The plate "adherends" and the plate "doublers" are considered as dissimilar, orthotropic "Mindlin Plates" with the transverse and the rotary moments of inertia. The relatively, very thin adhesive layers are taken into account in terms of their transverse normal and shear stresses. The mid-center of the bonded ...
Vibration Analysis of a Cracked Beam on an Elastic Foundation Batihan, Ali Cagri; Kadıoğlu, Fevzi Suat (2016-06-01) The transverse vibrations of cracked beams with rectangular cross sections resting on Pasternak and generalized elastic foundations are considered. Both the Euler-Bernoulli (EB) and Timoshenko beam (TB) theories are used. The open edge crack is represented as a rotational spring whose compliance is obtained by the fracture mechanics. By applying the compatibility conditions between the beam segments at the crack location and the boundary conditions, the characteristic equations are derived, from which the n...
Free bending vibrations of a centrally bonded symmetric double lap joint (or symmetric double doubler joint) with a gap in mindlin plates or panels Yuceoglu, U.; Guvendik, O.; Ozerciyes, V. (2007-11-16) In this present study, the "Free Bending Vibrations of a Centrally Bonded Symmetric Double Lap Joint (or Symmetric Double Doubler Joint) with a Gap in Mindlin Plates or Panels" are theoretically analyzed and are numerically solved in some detail. The "plate adherends" and the upper and lower "doubler plates" of the "Bonded Joint" system are considered as dissimilar, orthotropic "Mindlin Plates" joined through the dissimilar upper and lower very thin adhesive layers. There is a symmetrically and centrally lo...
ANALYTICAL INVESTIGATION OF AERO-ELASTIC BEHAVIOR OF AIRCRAFT COMPOSITE BOX WINGS IN UNSTEADY COMPRESSIBLE FLOW Farsadi, T.; Haddadpour, H.; Yuceoglu, U. (2011-11-17) In this study, an anisotropic thin-walled "Composite Box Beam" as the "Wing System" is used to consider the effects of the fiber orientation and the lay-up configuration on the aeroelastic stability and the dynamic response of an aircraft wing. The present "Circumferentially Asymmetric Stiffness Model (CAS)" takes into account a group of non-classical effects; such as the transverse shear, the material anisotropy, warping inhibition, etc. The "Aerodynamic Strip Method" based on "Wagner Functions" in unstead...
Free flexural (or bending) vibrations analysis of composite, orthotropic plate and/or panels with various bonded joints(--- in aero structural systems---) Güvendik, Özen; Yüceoğlu, Umur; Department of Aerospace Engineering (2004) In this أThesisؤ, the problems of the أFree Flexural (or Bending) Vibrations of Composite, Orthotropic Plates and/or Panels with Various Bonded Jointsؤ are formulated and investigated in detail. The composite bonded plate system is composed of أPlate Adherendsؤ adhesively bonded by relatively very thin adhesive layers.
