It is known that there are some problems about the mechanical system with both collision and rolling contact. But they haven't been discussed widely to solve more general cases with elasticity such as rubber tires of vehicles. So this study is focused on dynamic behavior of rolling elastic body in collision and understanding its mechanism. Then, the formulation is proposed for the state of contact of rolling ball in collision with considering the effect of sliding, friction and elasticity, in order to accomplish the numerical simulations for such a system. As the result, it is shown that there are some differences in the displacement and rolling speed after collision between the methods with elasticity and without it.
