Cosserat Continuum
Cosserat Continuum : A continuum, whose point bodies (infinitesimal particles) possess both translational and rotational degrees of freedom. In the Cosserat continuum, the stress tensor is asymmetric, and there exists a couple-stress tensor. Apart from the full Cosserat continuum, there exist a Cosserat pseudo-continuum, in which translations and rotations are not independent (in the linear approximation, the rotation vector equals curl u/2, where u is the translational displacement), and a reduced Cosserat continuum, in which rotations and translations are independent but the couple-stress tensor is zero
