Special exact curved finite elements. (English) Zbl 0760.65008
The author describes a type of curved elements suitable for solving contact problems of the second order in domains $$\Omega$$ whose boundaries $$\Gamma$$ consist of a finite number of circular arcs and a finite number of line segments. The suggested curved elements, so-called special exact curved finite elements, can be used not only along the boundary $$\Gamma$$ but also in the interior of $$\Omega$$ and are the natural generalizations of linear elements in the case of boundaries $$\Gamma$$ described above.
