| Abstract: | By means of an isoparametric transformation,the stiffness matrix and the effective nodeforces of the parallelogram element are calcnlatel. The computational results indicate thatthey are both apparent integral forms and the effective node forces can be obtained by way ofstatical effective principle. |
