Effect of Random Defects on Dynamic Response of Honeycomb Structures Zhijun Zhenga and Jilin Yub CAS Key Laboratory of Mechanical Behavior and Design of Materials, University of Science and Technology of China, Hefei, Anhui 230026, P.
Introduction Cellular metals have shown great potential applications as energy-absorbing materials.
Experimental investigation is the essential means to obtain the mechanical behavior of materials, but there are some limitations associated to dynamic tests of cellular metals [1].
Results and Discussion Different deformation patterns can be found in the dynamic crushing of cellular materials.
At a very high impact velocity, a progressive layer-by-layer collapse band forms from the impact end, and the deformation occurs like a shock wave propagating through the cellular materials.

Static, dynamic and acoustical properties of sandwich composite materials.
