Flexure analysis of functionally graded (fg) plates using reddy’s shear deformation theory

Abstract

This paper presents a study on bending performance of transversely isotropic functionally graded (FG) plate under transverse mechanical load. Computational and analytical tools are used to study the behavior of FG plates under bending. Analytical modeling is based on Reddy’s third order theory (TOT) and a finite element computational tool ABAQUS is used to model FG material through user defined subroutine UMAT. Elastic properties of FG material are based on power law and varying across the thickness of the plate while Poisson’s ratio is kept constant. Results from computational tools for a FG plate with standard boundary and loading conditions are validated with literature and TOT. After validation, FG plates with various boundary conditions are analyzed.
