“…The use of BEM has also been applied to homogeneous as well as to inhomogeneous materials, and not only to isotropic but also to anisotropic materials. For example, [1] used the BEM for solving infiltration problems of isotropic homogeneous media, [2] derived a fundamental solution, [3] considered diffusionconvection problems for anisotropic homogeneous materials, [4] solved elasticity problems for isotropic inhomogeneous materials and [5] studied elasticity problems, [6] worked on elliptic boundary value problems, [7] solved heat conduction problems, [8] worked on elasticity problems and [9] considered transient heat conduction problems for anisotropic inhomogeneous materials.…”
