Abstract

The present paper is concerned with the application of newly developed high-order semi-local smoothing splines (or S-splines) in solving problems in elasticity. We will consider seventh-degree S-splines, which preserve the four continuous derivatives (C 4-smooth splines) and remain stable. The problem in question can be reduced to solving an inhomogeneous biharmonic equation by the Galerkin method, where as a system of basis functions we take the C 4-smooth fundamental S-splines. Such an approach is capable not only of delivering high accuracy of the resulting numerical solution under a fairly small number of basis functions, but may also easily deliver the sought-for loads. In finding the loads, as is known, one has to twice numerically differentiate the resulting bipotential, which is the solution of the biharmonic equation. This results in roundoff propagation.
