There is a post of Tobi's eq-code explanation on viscous stress.

In incompressible flow, beside normal stress (taken out as p*I), the viscous part is only a function of deviate part of grad(U) (or its transpose).

In "SymmTensorI.H"
there are tow functions for deviate part of a tensor as explained by Tobi : dev and dev2
