Buckling analysis of single-layered FG nanoplates on elastic substrate with uneven porosities and various boundary conditions
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2018, Vol 15, Issue 5
Abstract
In this investigation the buckling behavior of single-layered functionally graded nanoplates with uneven porosities exposed to hygrothermal loads is modeled for the first time. Using the Eringen’s nonlocal elasticity theory with one scale parameters, the small size effect on the buckling behaviour of the functionally graded nanoplates is considered. Based on the new first order shear deformation theory the equations of equilibrium are obtained from the principle of minimum potential energy. Also, elastic Pasternak foundation is adopted to capture the foundation influence on the critical buckling load. The equations of equilibrium are solved for various boundary conditions using Galerkin’s method. The impacts of nonlocal parameter, porosity distribution and boundary conditions on the critical buckling load are demonstrated.‚
