Abstract: | |||||
In this thesis both static and dynamic analyses of composite thin-walled structures
are carried out. Most notably, the Dynamic Stiffness Method (DSM) has been extensively
exploited to develop advanced formulations for plates and shells. In particular,
the. Dynamic Stiffness (DS) matrices have been developed for laminated composite
plates and shells using Higher-order Shear Deformation Theory (HSDT) in order to
investigate their free vibration behavior and buckling characteristics. First, the Governing
Differential Equations (GDEs) of motion and associated natural Boundary
Conditions (BCs) (Neumann-type) for the given displacement field are derived via
Hamilton's principle for both composite plate and shell structures. In the case of
composite plates, the DS matrices are formulated for both out-of-plane and in-plane
deformations. The GDEs for each of the two cases are solved in Levy's form separately.
Next the problems for both plates and shells are reduced to a system of
ordinary differential equations which are then solved by using the classical exponential
solution procedure.
