In this paper the Carey non-conforming ยฎnite element is considered for solving eigenvalue problems of the second-order elliptic operator. Based on an interpolation postprocessing, high-accuracy estimates of both eigenfunctions and eigenvalues are obtained: Here, P 2 2h is an interpolation operator,
## Abstract The objective of the present study is to show that the numerical instability characterized by checkerboard patterns can be completely controlled when nonโconforming fourโnode finite elements are employed. Since the convergence of the nonโconforming finite element is independent of the L
