Microstructure-Based Modeling of Elastic Functionally Graded Materials: One Dimensional Case
Original language description
Functionally graded materials (FGMs) are two-phase composites with continuously changing microstructure adapted to performance requirements. Traditionally, the overall behavior of FGMs has been determined using local averaging techniques or a given smooth variation of material properties. Although these models are computationally efficient, their validity and accuracy remain questionable, since a link with the underlying microstructure (including its randomness) is not clear. In this paper, we propose anumerical modeling strategy for the linear elastic analysis of FGMs systematically based on a realistic microstructural model. The overall response of FGMs is addressed in the framework of stochastic Hashin-Shtrikman variational principles. To allow forthe analysis of finite bodies, recently introduced discretization schemes based on the finite element method and the boundary element method are employed to obtain statistics of local fields.
