Mechanics of Continuous Media in $({\bar{L}}_n,g)$-Spaces. IV. Stress (Tension) Tensor

Basic notions of continuous media mechanics are introduced for spaces with affine connections and metrics. Stress (tension) tensors are considered, obtained by the use of the method of Lagrangians with covariant derivatives (MLCD). On the basis of the covariant Noether’s identities for the energy-momentum tensors, Navier-Stokes’ identities are found and generalized Navier-Cauchy as well as Navier-Stokes’ equations are investigated over spaces with affine connections and metrics.
