<jats:p>In a recent paper [A. F. Bower and J. H. Weiner, J. Chem. Phys. 120, 11948 (2004)] we presented an extensive set of molecular dynamic simulations that examined the effects of confining pressure on the deviatoric stress-v-stretch behavior of a model rubber. In this note, we reconsider the implications of these data on the behavior of rubber under standard conditions. It is shown that simulations with realistic packing fractions predict stresses that are substantially larger than the predictions of the classical affine network model of rubber elasticity, suggesting that nonbonded interactions contribute significantly to the deviatoric stress even at standard conditions.</jats:p>
