Finite Element Modelling of the Functionally Graded Shells Mechanical Behavior

Abstract

In this study, numerical analysis of the static bending response of FGM is carried out with different combinaisons of geometries, boundary conditions and mechanical loading. The material properties according to the coordinates of the integration points are defined using the UMAT subroutines in ABAQUS software. The FSDT is used for thin and moderately thick FG shells analysis. The performance of the developed work is illustrated through the solution of several non trivial structure problems from literature. The numerical simulation depicts very close results to solutions in literature which assess the accuracy of the implementation. The proposed solution procedure is significantly efficient from the computational point of view.
