Abstract
This chapter deals with the theoretical background of granular dynamics and assembly mechanics. The complete set of equations required to perform three-dimensional DEM simulations are provided, dealing with particle kinematics, contact forces, timestep and damping. The chapter then considers various characteristics of compact particle systems with enduring contacts and provides derivations of the coordination number, fabric tensor, stress tensor and assembly modulus.
