Assessment of the Stress Distribution in a FG Beam-Type Structure Due to GDQ Method

In this paper, assessment of the stress distributionin a FG beam-type structure due to GDQ method has beenpresented. It is assumed that properties of the FG beamfollow a power law form through thickness. In addition,Poisson’s ratio is constant in the current work. The problemformulations of the stress distribution of the beam-typestructure is deduced by using FSDPT, Von Kármán-typenon-linearity strains, and principle of minimum totalpotential energy. In this case, GDQ method is used to solvethe PDEs by various weighting coefficients. Finally, theinfluence of the mechanical and geometry parameters onthe structure is illustrated by graphics.
