Abstract:

The proposed finite element model is based on separate assumptions of interior and interelement displacements and on the assumed boundary tractions of each individual element. The associated variational functional for this model is presented. This method has the same merits of the assumed stress method in that a compatibility displacement function at the interelement boundary can be easily constructed. In the plate bending problems, the matrix to be inverted to obtain the element stiffness matrix by the present method is, in general, of smaller order than that of the assumed stress method when the same order of approximation is used in both methods.
