Free vibration analysis of magnetoelectroelastic plate resting on a Pasternak foundation
Free vibration of a magnetoelectroelastic plate resting on a Pasternak foundation is investigated based on Mindlin theory. The in-plane electric and magnetic fields can be ignored for plates. According to the Maxwell equation and magnetoelectric boundary condition, the variation of electric and magnetic potentials along the thickness direction of the plate is determined. Using Hamilton’s princi...
متن کاملNumerical free vibration analysis of higher-order shear deformable beams resting on two-parameter elastic foundation
Free vibration analysis of higher-order shear deformation beam resting on one- and two-parameter elasticfoundation is studied using differential transform method (DTM) as a part of a calculation procedure. First,the governing differential equations of beam are derived in a general form considering the shear-freeboundary conditions (zero shear stress conditions at the top and bottom of a beam). ...
متن کاملMesh-free Dynamic Analyses of FGM Sandwich Plates Resting on A Pasternak Elastic Foundation
This study analyzes the free vibration, forced vibration, resonance, and stress wave propagation of orthotropic sandwich plates made of functionally graded materials (FGMs). Dynamic analyses are conducted using a mesh-free method based on first-order shear deformation theory and the shape functions constructed using moving least squares approximation. The sandwich plates are rested on a Pastern...
متن کاملOn the Theory of Beams Resting on a Yielding Foundation.
Introduction.-The purpose of this note is to advance the theory of the following problem: An elastic beam of infinite length, loaded inside a finite region, rests on a yielding foundation. It is asked how much the results of this theory are influenced by alterations of the assumptions concerning the physical nature of the foundation. As it is known, in engineering the assumption is made that at...
