A finite strain Raviart-Thomas tetrahedron
A finite-strain stress-displacement mixed formulation of the classical low-order tetrahedron element is introduced. The stress vector obtained from the face normals is now a (vector) degree-of-freedom at each face. Stresses conjugate to the relative Green-Lagrange strains are used within the framewo...
