Free and Forced Transverse Vibration Analysis of Moderately Thick Orthotropic Plates Using Spectral Finite Element Method
In the present study, a spectral finite element method is developed for free and forced transverse vibration of Levy-type moderately thick rectangular orthotropic plates based on first-order shear deformation theory. Levy solution assumption was used to convert the two-dimensional problem into a one-dimensional problem. In the first step, the governing out-of-plane differential equations are tr...
متن کاملVibration Analysis of Thin Cylindrical Shells Using Wave Propagation Approach
The vibration analysis of cylindrical shells using wave propagation method is presented. Results obtained using the method have been evaluated against those available in the literature. Comparison of the results by the present method and numerical "nite element method is also carried out. It is possible to conclude through the comparisons that the present method is convenient, e!ective and accu...
متن کاملAnalysis of Thin Shells by the Element-Free Galerkin Method
A meshless approach to the analysis of arbitrary Kirchhoff shells by the Element-Free Galerkin (EFG) method is presented. The shell theory used is geometrically exact and can be applied to deep shells. The method is based on moving least squares approximant. The method is meshless, which means that the discretization is independent of the geometric subdivision into “finite elements”. The satisf...
متن کاملVibration of Timoshenko Beam-Soil Foundation Interaction by Using the Spectral Element Method
This article presents an analysis of free vibration of elastically supported Timoshenko beams by using the spectral element method. The governing partial differential equation is elaborated to formulate the spectral stiffness matrix. Effectively, the non classical end boundary conditions of the beam are the primordial task to calibrate the phenomenon of the Timoshenko beam-soil foundation inter...
