摘要: Abstract As a first endeavor, the thermal buckling and postbuckling analysis of functionally graded (FG) annular plates with material properties in radial direction is presented. The formulation derived based on first-order shear deformation theory (FSDT) geometrical nonlinearity modeled using Green’s strain conjunction von Karman’s assumptions. are temperature-dependent according to power law distribution. It assumed that temperature varies along direction. Using virtual work principle, pre-buckling equilibrium equations related boundary conditions derived. Differential quadrature method (DQM) as an efficient numerical technique adopted solve governing equations. presented solution validated by performing convergence comparison studies available results literature. Finally, effects volume fraction index, parameters, mechanical/thermal constituent materials behavior radially plate evaluated discussed.
