Effect of Rolling Resistance in Dem Models With Spherical Bodies

Effect of Rolling Resistance in Dem Models With Spherical Bodies Abstract The rolling resistance is an artificial moment arising on the contact of two discrete elements which mimics resistance of two grains of complex shape in contact rolling relatively to each other. The paper investigates the influence of rolling resistance on behaviour of an assembly of spherical discrete elements. Besides the resistance to rolling, the contacts between spherical particles obey the Hertzian law in normal straining and Coulomb model of friction in shear. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Transactions of the VŠB – Technical University of Ostrava, Civil Engineering Series. de Gruyter

Abstract

Abstract The rolling resistance is an artificial moment arising on the contact of two discrete elements which mimics resistance of two grains of complex shape in contact rolling relatively to each other. The paper investigates the influence of rolling resistance on behaviour of an assembly of spherical discrete elements. Besides the resistance to rolling, the contacts between spherical particles obey the Hertzian law in normal straining and Coulomb model of friction in shear.
