Box 11155-4563, Iran Journal Article 2015 09 11 In this paper, an analytical formulation is presented to study an exponentially graded transversely isotropic tri-material under applied axisymmetric point-load and patchload with the aid of Hankel transform and use of a potential function. 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 presented<br />to explain inhomogeneity eect on the stress transfer process in the inhomogeneous threelayered medium by means of a fast and accurate numerical method. https://scientiairanica.sharif.edu/article_4080_26175b101812b4f22012ffeaa811784d.pdf
