A Hill-based computational homogenization approach for effective elastic properties of Kelvin open-cell foams
Résumé
he aim of this study is to investigate the influences of morphological parameters on the effective elastic properties of Kelvin open-cell foam. To obtain realistic cell structure, a method based on Voronoi partition combined with Surface Evolver is developed with high control of a number of morphological parameters. The periodic computational homogenization approach is used to predict the elastic effective properties. Finally, new generic laws are proposed to approximate the effective elastic properties of Kelvin open-cell foam.
