ResumoA finite element model for the analysis of two-dimensional elastic problems is presented. The proposed discretization is based on a biquadratic interpolation for the displacement components and takes advantage of the enforcement of the interelement continuity to obtain a profitable reduction of the total number of the degrees of freedom. One node (two kinematical parameters) per element only is required. Numerical results obtained for some test problems show the accuracy of the model in analyzing both the deformations and the stress distribution.
