Abstract
We examine the jamming transition in a two-dimensional granular polymer system using compressional simulations. The jamming density decreases with increasing length of the granular chain due to the formation of loop structures, in excellent agreement with recent experiments. The jamming density can be further reduced in mixtures of granular chains and granular rings, also as observed in experiment. We show that the nature of the jamming in granular polymer systems has pronounced differences from the jamming behavior observed for polydisperse two-dimensional disk systems at point . This result provides further evidence that there is more than one type of jamming transition.
