Buckling of Functionally Graded Plates with Varying In-Plane Loading
Abstract
Functionally graded materials are materials with a spatial variation of material properties. The FGM plates have significant applications in turbine blades, helicopter blades, compressor blades, aircraft or marine propellers. Many of these plates are subjected to in-plane load due to fluid or air pressure. Hence it is necessary to study their behavior under different types of loads .Study of buckling of functionally graded material (FGM) plates with different boundary conditions under varying in-plane load is therefore an important study. In these days, FGM have many engineering applications because of their high stiffness and strength.The analysis is completed utilizing ANSYS programming. In ANSYS, the SHELL 281 component with six degrees of freedom per node is utilized. Twelve by twelve mesh and twelve layers were chosen for the analysis as per the results obtained in convergence study. Buckling of FGM plates with different in plane loading are studied. The effect of different parameters like width to thickness proportion, aspect ratio, gradient index and boundary conditions on the buckling load of FGM plates with varying in-plane load were studied.
