Compressive response of circular cell polycarbonate honeycombs under inplane biaxial static and dynamic loading—Part II: simulations

The static and dynamic experimental results of a polycarbonate circular cell honeycomb subjected to inplane biaxial loading are simulated through numerical analysis using the finite element method. The experimental results were presented in Part I of this two part paper (Chung and Waas, Int. J. Impact Eng. (2001), in preparation). Through several comparisons between the experimental and numerical results, the biaxial inplane crushing mechanisms of the circular cell honeycomb material are studied. The finite element simulations are able to accurately capture the essential features observed and measured in the experiments.
