AN ANALYSIS OF FUNCTIONALLY GRADED MATERIALS BY THE ISOPARAMETRIC GRADED FINITE ELEMENT METHOD BASED ON ABAQUS

Abstract

Abstract: Based on the computing platform of the finite element method (FEM) commercial software ABAQUS, a plane structure of functionally graded materials (FGMs) is analyzed by finite element models which are based on the isoparametric graded finite element method (IGFEM). Numerical example shows that the stress and displacement results by the IGFEM are satisfactorily agreed with the analytical solutions. By designing Young's Modulus nonhomogeneity parameters of material component Y-TZP in three cases, the influence on the FEM solutions is discussed. By the numerical example of the FEM fine mesh, it is found that the IGFEM has high accuracy and better convergence.

Key words: functionally graded materials, isoparametric graded finite element, nonhomogeneity parameters, finite element analysis
