Abstract :
In this paper, an analytical formulation is presented to study an exponentially
graded transversely isotropic tri-material under applied axisymmetric point-load and patch- load
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 finite 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 to explain
inhomogeneity effect on the stress transfer process in the inhomogeneous three-
layered medium by means of a fast and accurate numerical method.
