Abstract

POROUS MATERIALs are lightweight, flexible and resistant to hairline cracks. So today with the development of technology porous structures are produced for use in various industries. These structures are widely used in beams, plates and shells. The purpose of this paper is to analytically investigate the effect of porosity on axial symmetry plane of sheet metals with BENDING and buckling loads. For this purpose, a circular plate with simply supported edges under uniform radial pressure and vertical pressure distribution is investigated. Mechanical properties of porous sheets are isotropic in sheet plane and variable in thickness direction. Field displacement is extended in accordance with the FIRST ORDER SHEAR DEFORMATION THEORY. Then, using the principle of virtual work and applying the calculus of variations, differential equations, and equations for BENDING sheet stability are achieved. Continuing the used of these equations and Galerkin method, BENDING and buckling of the sheet is calculated. Buckling load is calculated for all types of porosity can be observed with increasing porosity, critical buckling load decreases. The distribution of BENDING stress and deflection in sheet analysis was obtained. To verify the results of BENDING and buckling of the sheet, the results were compared with the homogeneous sheet with classical theory.
