TL;DR: In this paper, the standard bilinear displacement field of the plane linear elastic rectangular 4-node quadrilateral element is enhanced by incompatible modes and the resulting gradient operators are separated into constant and linear parts corresponding to underintegration and stabilization of the element stiffness matrix.
Abstract: The standard bilinear displacement field of the plane linear elastic rectangular 4-node quadrilateral element is enhanced by incompatible modes. The resulting gradient operators are separated into constant and linear parts corresponding to underintegration and stabilization of the element stiffness matrix. Minimization of potential energy is used to generate exact analytical expressions for the hourglass stabilization of the rectangle. The stabilized element is shown to coincide with the element obtained by the mixed assumed strain method.
