    Abstract

    The aim of this paper is to study the mechanical tensile properties of open-cell foam structures on the cell size variation by numerical simulations. For this purpose, random Laguerre tessellations were used, which allow the creation of foam structures with strongly varying cell sizes. First, a model was fitted to real open-cell foams based on x-ray computed tomography (XCT) scans by parameter optimization. Two more virtual foam models with different cell size variations were produced according to the first fitted one. Tensile properties of the model realizations were computed by finite-element analysis using beam elements. The numerical results were presented and discussed.
