\begin{eqnarray*}\kTb=\dot{\Tb}-\Wb\Tb+\Tb\Wb \quad. \end{eqnarray*}

$\kTb$ is the co-rotational or ZAREMBA or JAUMANN stress rate. $\kTb$ is the stress change that results solely from the deformation of the considered material, whereas any apparent parts (due to rotations of the observer or of the reference frame) are removed.
