Green's functions and boundary element method formulation for 3D anisotropic media

The implementation of Wang's theoretical solution is presented for elastost atic displacement Green's function for three-dimensional solids of general anisotropy. Excerpts from the authors' FORTRAN code are included. A numeric al algorithm for the calculation of the derivatives of the Green's displace ments and stresses is also introduced. These implementations have been inco rporated into a boundary element method (BEM) code developed by the authors . The numerical results of Green's displacements, stresses and stress deriv atives are in perfect agreement with closed-form solutions for transversely isotropic solids. The BEM code results are also in very close agreement wi th both exact solutions and other BEM formulations, even if coarse mesh dis cretizations are used. (C) 2001 Elsevier Science Ltd.
