Effect of particle shape on bulk-stress-strain relations of granular materials

The effect of the particle shape on the bulk-stress-strain-relations for triaxial compression of granular media is investigated via the molecular dynamicsmethod. It is found that crucial properties exhibited by experimental granular media cannot be reproduced by round particle simulations, but only by theuse of elongated particles.
