Multi-body contact interactions are crucial in accurately modelling systems where multiple solid bodies come into contact, such as mechanical assemblies, granular flows, or fractured materials. These interactions involve the calculation of contact forces and deformations between different bodies, which can be challenging due to the nonlinearity and complexity of contact mechanics. DEM, is often used to model these interactions, enabling the prediction of contact forces, frictional behaviour, and resultant deformation. This is particularly important in simulations where contact conditions significantly affect the system's performance and stability, such as during rock faulting, and catastrophic failure of structures.
