| Abstract Scope |
While much is known about how aperiodicity influences the mechanical behavior of cellular materials, this work seeks to answer why it does so. It proposes a new, multiscale approach, arguing that there is a “missing link” between relating local deformation in cellular materials and their global response – and further, proposes quantification of the meso-structure as the central analysis that needs to be conducted to close this gap. Honeycombs with increasing levels of perturbation are used to demonstrate this, finding hitherto unreported correlations between effective elastic moduli and the standard deviation of the strain component along the loading direction, which itself depends on the standard deviation of the normalized beam length. This study hints at the potential for uncovering new insights by leveraging a multiscale approach that combines global stress-strain response, mesostructural quantification and local point-wise strain information into an integrated statistical analysis. |
