Abstract

In this brief study, the stress is averaged over a two-dimensional rigid particle (disk) that is in contact with other objects via localized (point) contacts. In contrast to previous studies, the rotation dynamics of the particles is also taken into account here The stress contains four terms, (i) the static stress due to forces, (ii) the dynamic stress due to translational velocity fluctuations, (iii) the dynamic stress due to rotational velocity fluctuations, and (iv) the stress due to changes of angular velocities due to torques.
