Abstract
AbstractAn easy to use stability test is presented for finite elements which are under‐ or selectively‐integrated. This test is reminiscent of the patch test in that it must be applied only to one prototype element, and it is a sufficient test for the nonsingularity of the global coefficient matrix. The minimum number of integration points which can be used with each of several common one‐, two‐ and three‐dimensional elements for a variety of steady‐state and time‐dependent, scalar boundary value problems are given.
