Abstract
This short paper demonstrates how the matrix for a 4-node potential fi nite element can be derived from the conditions of 'rigid body movemen t',dagger symmetry and consistency, and the requirement that the eleme nt solve exactly the case of phi = xy. This derivation is intended to be a simple illustration of the ideas of Bergan and others. (C) 1998 J ohn Wiley & Sons, Ltd.
