摘要：

The paper presents a numerical study of the normal impact of elastoplastic spheres with a rigid wall. The analysis is performed by employing DYNA2D, a non-linear, explicit, two-dimensional finite element (FE) code for impact mechanics. Deformations, time evolution of the contact force and contact force-displacement relationships during the impact are presented. Influences of material behaviour are discussed and their effect on the coefficient of restitution is also demonstrated.
