Abstract
A four-node quadrilateral element is presented which shows promise for general compressible and incompressible two-dimensional analysis of s olids and fluids. The element is based on a mixed interpolation of dis placements (velocities), pressure and strains (velocity strains). We s how that the element satisfies a numerical inf-sup test, and give resu lts of some analysis problems that demonstrate the capabilities of the element.
