Peridynamics-based discrete element method (PeriDEM) model of granular systems

Implementation of the high-fidelity model of granular media that combines the advantages of peridynamics and discrete element method (DEM). The model has the following advantages over existing mechanical models for granular media:

• handle intra-particle deformation and breakage/damage
• handle arbitrary shape of the particle. Inter-particle contact is not specific to any shape of the particle
• tunable inter-particle contact parameters
• easy to add different mechanical constitutive laws within peridynamics for individual particle deformation

For more details about the model and results, we refer to the paper:
