In this paper, the behavior of free vibrations and buckling of the sandwich panel with a flexible core was investigated using a new improved high-order sandwich panel theory. In this theory, equations of motion were formulated based on shear stresses in the core. First-order shear deformation theory was applied for the procedures. In this theory, for the first time, incompatibility problem of...
Free vibration analysis of functionally graded rectangular plates via differential quadrature method
In this study, free vibration of functionally graded rectangular plates for various types of boundary conditions has been presented . The properties of the plate are assumed as power- law form along the thickness direction , while poisson's ratio is kept constant. the linear vibration equations of functionally graded rectangular plates are derived based on first order shear deformation theory b...
Several vibro-acoustic models for either single wall or multi-layer constructions are based on classical plate and first order shear deformation theories. The equivalent condensed employ the thin model to extract dynamic mechanical properties of system considering only flexural motions structure under investigation. Since these do not account compressional symmetric motion structure, both thick...
In this paper, a displacement-based, variationally consistent, two variable refined theory for shear deformable beams is presented. The beam is assumed to be of linearly elastic, homogeneous, isotropic material and has a uniform rectangular cross-section. In this theory, the beam axial displacement and beam transverse displacement consist of bending components and shearing components. The assum...
