The analytical expressions are developed for elastic deformation provided the pressure function on a nine-node element of any nonequidistant rectangle is approximated by a biquadratic polynomial. Using the present scheme, the coefficients Aij showing in pressure solution are simply calculated once enough in the full iterations. The computational works are greatly reduced.
