Creep Behavior of Functionally Graded Material under In-Plane Bending Moment

Abstract:

The creep behavior of functionally graded material under in-plane bending moment is investigated in this paper. By extending the classic beam theory an analytical model is proposed to predict the distributions of creep strain and creep stress inside the functionally graded material according to the relationship between the inclusion volume fraction and composite creep coefficient. The analytical solution agrees well with the results obtained by the finite element method and the basic knowledge about time-dependent behavior of functionally graded material is achieved to guide its design and fabrication.
