✦ Synopsis
This short paper demonstrates how the matrix for a 4-node potential ®nite element can be derived from the conditions of `rigid body movement',{ symmetry and consistency, and the requirement that the element solve exactly the case of f xy. This derivation is intended to be a simple illustration of the ideas of Bergan and others.
