Abstract
This paper considers the solution of problems in three-dimensional solid mechanics using tetrahedral finite elements. A formulation based on a mixed-enhanced treatment involving displacement, pressure and volume effects is presented. The displacement and pressure are used as nodal quantities while volume effects and enhanced modes belong to individual elements. Both small and finite deformation problems are addressed and sample solutions are given to illustrate the performance of the formulation. Copyright © 2000 John Wiley & Sons, Ltd.
