Finite calculus formulation for incompressible solids using linear triangles and tetrahedra - Olgierd Zienkiewicz (International Journal for Numerical Methods in Engineering, 2004)
Automatic mesh generators generally produce unstructured meshes consisting of linear simplex elements. These elements are known to cause problems when applied in many incompressible solid mechanics simulations. This paper describes a novel method which demonstrates how these elements may be stabilised for practical use.
