OICC Press Journal of Solid Mechanics 2008-7683 1 2 2009 07 30 Effect of Non-ideal Boundary Conditions on Buckling of Rectangular Functionally Graded Plates 91 97 EN J Mohammadi Department of Mechanical Engineering, Islamic Azad University, Arak Branch M Gheisary Faculty of Engineering, Islamic Azad University, Khomein Branch Journal Article 2009 07 30 We have solved the governing equations for the buckling of rectangular functionally graded plates which one of its edges has small non-zero deflection and moment. For the case that the material properties obey a power law in the thickness direction, an analytical solution is obtained using the perturbation series. The applied in-plane load is assumed to be perpendicular to the edge which has non-ideal boundary conditions. Making use of the Linshtead-Poincare perturbation technique, the critical buckling loads are obtained. The results were then verified with the known data in the literature.
