Abstract
The paper deals with the boundary element discretization of plates based on the Kirchhoff and the Reissner models. The discretization uses a macro-element management with independent interpolation fields, which allows the inclusion of discontinuities in the boundary data, and on a quadratic B-spline approximation of the boundary variables. The analytical evaluation of integrals is used everywhere within the Kirchhoff model, while in the Reissner model the Bessel functions, which appear in the fundamental solution, require some numerical integrations. The numerical experiments refer to non-smooth problems, having mixed boundary conditions and skew domains. The results are compared with finite element and other boundary element results.
