Abstract :

Foams are cellular materials with unique mechanical properties. The geometric properties of these structures have been proved to be responsible for their unique mechanical properties. In the process of modeling and simulation, reproducing those geometric properties accurately is still a challenge to researchers. This paper provides details on the geometric modeling techniques used to model the foams and investigates the effects of the initial seed points on the geometric and mechanical properties. Unit cell repetition methods such as Kelvin cell, Gibson-Ashby cell as well as randomly generated models such as Poisson Voronoi, Hardcore Voronoi, and Laguerre Voronoi were all investigated and their effectiveness in reproducing the geometric properties of the foams and predicting the elastic properties is demonstrated.
