摘要：

The matrix power series expansion is used for deriving the static geometric stiffness and elastic stiffness matrix of a hybrid displacement model. No restrictions about the number of interpolation functions within the interior of the element are introduced. The generalized degrees-of-freedom are not defined on nodal points but in an abstract way on element boundaries. Plate bending problems are considered to demonstrate the method. © 1978.
