Numerical investigation on buckling of two-directional porous functionally graded beam using higher order shear deformation theory
A large part of functionally graded materials is influenced by pores. By gradually expanding the distribution of pores from the surface to the interior, many features can be added. The amount and distribution of porosity have an impact on the materials Young’s modulus and tensile strength. 2D-functionally graded porous beams are exposed to different sets of boundary conditions using a third-order shear deformation theory. According to the power-law distribution, the properties of the beam’s material vary in both the axial and thickness directions. Axial and transverse deflections with in the cross sections could be written in polynomial formulations to calculate buckling load. Auxiliary functions are combined with the displacement functions to meet the boundary criteria. Three boundary conditions are taken into account: simply-supported, clamped-free, clamped–clamped. The results obtained are compared to prior attempts at convergence and verification studies. On buckling reactions of 2D-functionally graded porous beams, the impact of various aspect ratios, boundary conditions, and gradient indices is examined.
