✦ Synopsis

Computer programs are given for calculating the three primitive matrices for tetrahedral finite elements. These may be employed to create finite element representations of arbitrary linear differential operators in three-dimensional spaces. Use of these primitives is recommended for second order operators, since the approximating functions employed have CO continuity, and incompatible elements may be generated for fourth or higher order operators.

This paper considers the solution of problems in three-dimensional solid mechanics using tetrahedral ΓΏnite elements. A formulation based on a mixed-enhanced treatment involving displacement, pressure and volume e ects is presented. The displacement and pressure are used as nodal quantities while vol
