Lateral Crushing of Circular Rings Under Wedge Impact

The present work is concerned with the dynamic behavior of a circular ring loaded between a wedge-shaped indenter and a rigid plate. First, an analytical model using the rigid-plastic theory is established. The effects of strain-hardening and strain-rate are incorporated. The history of displacement, velocity and reaction force of the wedge-shaped indenter and energy absorbed by the circular ring are obtained. Further, to verify the proposed analytical model, numerical simulations and experiments are performed and compared with the analytical predictions. It is found that the analytical solutions compare well with the numerical simulations and experiments. This study provides a better understanding of the energy dissipation behavior of circular rings.
