Abstract
- In this study, mechanical performance of octagonal structure subjected to out-of-plane compression was investigated theoretically and numerically. Theoretical derivation was carried out according to super folding element, formulas were constructed in terms of relative density, half-wave length, average force, mean stress as well as specific energy absorption (SEA). To validate, full scale numerical finite element (FE) models were created to analyze the mechanical behavior of the present structure computationally. Analytical solutions were in good agreement with computational results. Parametric study shows that different geometric configurations heavily influence the mechanical performances. Detailed comparisons between octagonal and conventional hexagonal honeycomb were performed. [ABSTRACT FROM AUTHOR]
