The coefficient of restitution for the impact of a compound pendulum with a flat surface is an important quantitative measure in contact analysis. The impact is analyzed for different lengths of the pendulum, different angles of impact, and different initial angular velocities of the pendulum. The impact with friction is studied using an elasto plastic force developed by Jackson and Green for the three phases of impact: elastic compression, elasto-plastic compression, and elastic restitution phase.
