Deflection Analysis of straight FGM beam with different parameters

This paper deals with the deflection analysis of Straight functionally Graded Beam (FGM) considering various parameters. It is analysed with different boundary conditions like simply supported, clamped-clamped. The FGM beam is analysed for different L/h ratio and different volume fraction index. is analysed with different L/h ratios using higher order shear deformation theory. It was found that for a fixed value of L/h ratio as the volume fraction index is increased the maximum deflection of FGM beam also increases. Again, if the value of volume fraction index is kept constant and the L/h ratio is increased the maximum deflection also decreases. The dependence of support conditions on maximum deflection is highlighted. Comparison and convergence study has been performed to validate the present formulation. Thus, we observe that for both clamped -clamped and simply supported condition, for a fixed value of of L/h ratio as the volume fraction index is increased the maximum deflection is increased. Again, if the value of volume fraction index is kept constant and the L/h ratio is increased the maximum deflection increases.
