Abstract

The objective of this contribution is to exist a numerical simulation technique to model the collision of particles in a plane using object-oriented procedures. This approach is based on the second law of Newton for the translational motion of each particle in the granular material. This comprises a possession track of all forces acting on each particle at every time-step. The back-ground version of DEM and time integration algorithm are established and executed into C++ code. A simple test is regarding the application of timeintegration algorithm by particle-particle interaction for which analytical expression exist. In this paper effect of elastic, elastic damping and elastic damping gravitational effect are studied and the trajectory of particle motion for different time integration scheme verses time step for particle – particle contact are calculated.
