Dynamic Energy Absorption of Circular Honeycomb under In-plane Impact Loading

摘要：

To effectively control the dynamic energy absorption, a density graded circular honeycomb model is proposed, based on the concept of functionally graded materials. The influences of density gradient and impact velocity on the dynamic energy absorption ability of circular honeycomb are investigated by adopting explicit dynamic finite element method. Numerical results show that the density gradient affects greatly in the energy absorption. These findings will provide valuable suggestions in the dynamic energy absorption design of cellular materials.
