Practical Jointed Approach to Functionally Graded Structures

Abstract

In this study, a practical jointed approach in the forced vibration investigation of functionally graded material (FGM) structures under internal pressure are applied by modified Durbin’s method. The FGM material consists of heterogeneous material that shows exponential variation in the thickness. Four types of dynamic loads are applied to the FGM cylinder for forced vibration. Displacement and stress distributions due to non-homogeneous constant are intended. Stress distribution dependent on the homogeneity parameter is computed and the results obtained for cylindrical structures were compared with the finite element method (FEM). The inhomogeneity parameter is empirically regulated, with a continuously changing volume fraction of the ingredients. The parameters for homogeneity were randomly selected to show displacement and stress distributions.
