In this paper a new algorithm and numerical approach which gives two-sided approximations of eigenvalues for second-order problem is presented. Conforming finite element methods are used in combination with an appropriate nonconforming interpolation. Numerical Aspects are discussed and also experiments which demonstrate the proposed algorithm are given.
