ABSTRACT
The crucial point on which we concentrate is the fact that for any sheared dense granular systems, there exist velocity regimes for which elastic energy is the dominant mode of energy storage. In such a setting, neither kinetic granular temperature, Tk , nor TE is likely to provide a good measure of the random nature of the system. In this context, we propose an extension of granular “temperature” that contains information on fluctuations of the elastic energy. To carry out this exploration, we use DES of 2D particles that are subject to plane shear and (possibly) compression.
