In this article, an exact analytical solution for thermal buckling analysis of thin functionallygraded (FG) rectangular plates is presented. Based on the classical plate theory and using the principle ofminimum total potential energy, the stability equations are obtained. Since the material properties in FGmaterials are functions of the coordinates (specially the thickness), the stability equat...

In this paper, the modified couple stress theory is used to study vibration analysis of functionally graded rectangular micro-plates. Considering classical and first order plate theories, the couple governing equations of motion are obtained by using the Hamilton’s principle. Considering an assumed mode method, the accurate size dependent natural frequencies are established for simply supported...

Transverse displacement divided into three parts: bending, shear, thickness stretching. Using Airy stress function, cor...

In this work, the quasi-3D hyperbolic shear deformation theory (quasi-3D HSDT) is utilized to examine dynamics of thick rectangular plates reinforced with nanofillers known as graphene nanoplatelets (GNPs). Agglomeration GNPs incorporated and mechanical characteristics like shear, elastic, bulk moduli, Poisson's ratio, density are analysed according mixture along Eshelby-Mori-Tanaka approach. H...
