Modeling the microstructure of biopolymer aerogels using Voronoi tessellation method

The bulk properties of biopolymer aerogels depend on their microstructure, which can be tailored by different synthesis and drying methods. Biopolymer are characterized a fibrillar morphology having cellular-like network. recently proposed constitutive modeling approach Rege et al. [1] has shown good predictive capabilities in describing the mechanical behavior such aerogels. Although model describes cellular nature adheres to cell-size distributions aerogels, it is based assumption that network made up idealized square-shaped cells. In this contribution, diversified described computationally using Laguerre-Voronoi tessellation [2]. pore-size distribution (PSD) data obtained from experiments accounts for random cell sizes within Accordingly, Voronoi tessellations generated create periodic representative volume elements (RVEs) resembling microstructural This work an extension our previous tessellation-based 2-d description [3].
