Among the foundations of continuum mechanics is the description of constitutive forces in terms of a symmetric tensor. Noll showed that this is a consequence of the axiom of material frame indifference [Nol,Tru], what in turn means a local invariance of the system under the Euklidean group. Here we will prove that the assumption of locality in this axiom is redundant to obtain the same result. We model a non-local system by means of a virtual work [AnOs,EpSe]. Under the global demand that this functional does not respond on rigid infintesimal motions, we show the existance of a symmetric stress tensor as a local result. As the mathematical tool for the localization we use the Hodge theory on manifolds with boundary.
