When a dynamic behavior with large displacements is analyzed by Newmark
method, the momentum and kinetic energy are known to be unable to
conserve, after long duration of its motion.
This case shows the effectiveness of the combination of two different time
integration method, which are applied to two sub-divided time steps,
regarding the dynamic force transmission of gear teeth.
