The given formulation is shown to be reducible to the special cases of (1) an inhomogeneous nite layer on a rigid base; (2) exponentially graded bi-material or half-space under applied buried loads; (3) homogeneous tri-material or bi-material solid. Several numerical solutions are presentedto explain inhomogeneity e ect on the stress transfer process in the inhomogeneous threelayered medium by means of a fast and accurate numerical method.}, keywords = {Functionally graded material,Exponentially graded,Transversely isotropic,Displacement potential,Tri-material,Axisymmetric green's function}, url = {https://scientiairanica.sharif.edu/article_4080.html}, eprint = {https://scientiairanica.sharif.edu/article_4080_26175b101812b4f22012ffeaa811784d.pdf} }
