| Abstract: | In this paper,the modified complmentary energy principle isemployed to derive the stiffness matrices of hybrid strcss elements.In applying the hybrid elements to analyze the plane pro blems,it turns out that the new elements are of higher accuracy.Thesame degree of accuracy in the results can be achieved withoutthe use of a large number of elements.The reduction in the numberof the elements generally reduces the effort needed in the prepara-tion of the data.Moreover,the complex problems can be solved ona computer with a smaller storage. |
