This paper investigates the dynamic behavior of elastoplastic collision of several non-sphere particles through the spherical element combination method. The particles are cylinder, triangle and square particles, which are combined by 2, 3 and 4 spheres using the spherical element method, respectively. Results reveal that the collision of the evaluated irregular particles exhibits three contact styles, which are single point contact, instantaneous multi-point contact and sequential multi-point contact. Normal contact torque and frictional torque act together on the spin of a particle and causes sequential multi-point contact under certain conditions for square particles.
