fis-1267	Maurelli, Giacomo; Maini, Nadia; Venini, Paolo	Mixed methods for viscoelastodynamics and topology optimization	2014	13	.pdf	application/pdf	5297	200	59	As to the stresses, one should notice that the symmetry of the stress tensor is imposed strongly so that the components to be approximated are 11 22 12, ,   and one ends up with 24 degrees-of-freedom:  the three components of the stress tensor 11 22 12, ,   at each vertex of the triangle (9 dofs),  the moments of order zero and one of the traction vector n  along each edge of the triangle (12 dofs),  the averages of the components of the stress tensor over the triangle, i.e. 11 22 12, , T T T      (3 dofs).
