The method of fundamental solutions for nonlinear functionally graded materials

In this paper, we investigate the application of the method of fundamental solutions (MFS) to two-dimensional steadystate heat conduction problems for both isotropic and anisotropic, single and composite (bi-materials), nonlinear functionally graded materials (FGMs). In the composite case, the interface continuity conditions are approximated in the same manner as the boundary conditions. The method is tested on several examples and its relative merits and disadvantages are discussed.
