ABSTRACT

In this paper, the time-domain dynamic response of a thick hollow cylinder made of two-dimensional functionally graded material is studied. An axisymmetric solid spectral finite element model is proposed for the analysis of elastic wave propagation in the cylinder. The effectiveness of the proposed model is verified by comparing with the conventional finite element method. The effect of material grading pattern is analyzed. The results demonstrate the effectiveness of the present method for the analysis of elastic wave propagation in functionally graded solids with axial symmetry and the material composition variation has an important effect on structural wave propagation behavior.
