Buckling analysis of an orthotropic porous circular plate resting on an elastic foundation in Thermal Environment

In the present investigation, buckling analysis of orthotropic porous circular plate with simply supported edge under radial uniform compressive load and thermal environment is studied. The plate is resting on Winkler-type foundation and Classical Plate Theory (CPT) with approximate solution by Rayleigh-Ritz method is employed and obtained critical buckling load of porous circular plate. The variational approch is used to derive the governing differential equations of the plate. Mechanical properties of the porous material are varied continuously through the thickness of the plate. The obtained results for porous plates are compared with some available in literature as homogeneous and porous circular plates with other conditions.
