Abstract
Interpolated one-dimensional finite elements are constructed and applied to the fourth-order self-adjoint elliptic boundary-value problems. A superconvergence postprocessing approach, based on the patch-recovery method, is presented. It is proved that the rate of convergence depends on the different variational forms related to the variety of the corresponding elliptic operators. Finally, numerical results are presented.
