The Dynamic Response of the Clamped Beam under Low Velocity Impact
A simplified theoretical model about the impact energy and maximum deflection was acquired based on the principle of virtual work while clamped beam subjected to low velocity impact. Finite element simulations have been undertaken to further understand the response of the clamped beam, the results show that: A good agreement has been obtained between theoretical model and numerical results, the dynamic response of the clamped beam is divided into four stages: elastic fluctuation, the overall structural response, unloading response and free vibration, the formation of plastic hinge occurred in the overall structural response stage.
