Conditions for Traceless Symmetric Improved Stress-Energy

A set of coupled equations, linear in the traceless tensors, for the shear rate and the rate of orientation as a function of the stress tensor and the degree of orientation, enables to derive expressions for the (complex) viscosity and the (complex) normal stress coefficients both in stationary and periodic shear, and, for the complex viscosity, also in parallel superposition of these two stress-energy tensor as before, namely by (6), it cannot be expected that we still have τk i,k = 0, but neither τk i;k, since, in general, τ k i is not even a covariant object (nevertheless, we will continue to refer to it as canonical tensor) and therefore the use of a covariant derivative does not seem to make much sense. Jul 19, 2020 · The Stress Tensor. Stress is defined as force per unit area. If we take a cube of material and subject it to an arbitrary load we can measure the stress on it in various directions (figure 4). These measurements will form a second rank tensor; the stress tensor. The following double sum generates all the terms of the stress tensor: The first line generates the energy density W, and part of the +0.5 delta(a, b)(E^2 + B^2) term of the Maxwell stress tensor. The rest of that tensor is generated by the second line. The third line creates the Poynting vector.
