A coupled 3D isogeometric and discrete element approach for modeling interactions between structures and granular matters

A three-dimensional (3D) isogeometric/discrete-element coupling method is presented for modeling contact/impact between structures and particles. This method takes advantages of the geometry smoothness and exactness of isogeometric analysis (IGA) for continuous solid media and the effectiveness and flexibility of the discrete element method (DEM) for particulate matters. The coupling procedure for handling interactions between IGA elements and...
