One sphere is in a horizontal position with gravitational acceleration, base acceleration and is given an initial velocity in the vertical direction. The other sphere is in the vertical direction. The spheres are treated as rigid bodies while no contact or deformation occurs (i.e., when the horizontal pendulum swings down towards the vertical pendulum). The spheres are switched to deformable through a restart file so that they become flexible during contact. Model: Both spheres are modeled using shell elements. The pendulum wires are modeled using elastic beams. Automatic single surface contact is used during the impact phase. Reference: Reid, J.D.
