    "abstract": "This paper deals with the complex problem of how to simulate multiparticle\ncontacts. The collision process is responsible for the transfer and dissipation\nof energy in granular media. A novel model of the interaction force between\nparticles has been proposed and tested. Such model allows us to simulate\nmultiparticle collisions and granular cohesion dynamics.",
