Geometric and finite element modeling of biopolymer aerogels to characterize their microstructural and mechanical properties
نویسندگان
چکیده
Biopolymer aerogels belong to a class of highly open-porous cellular materials. Their macroscopic mechanical properties (such as elasticity or thermal conductivity) depend on microstructural features (namely pore size distribution (PSD), fiber diameter and solid fraction), which can be tailored by different synthesis drying routes. The design modern aerogel materials requires better perception into the microstructure its influence properties. To predict material using simulation, it is significant construct geometric model sufficiently precise represent real A tessellation approach based Voronoi diagrams powerful tool such cellular-like In this contribution, diversified morphology described computationally tessellation-based [1]. Accordingly, tessellations are generated create periodic representative volume elements (RVEs) resembling network. Stress-strain curves resulting from finite element simulations these RVEs experiments under compression compared. This work an extension our previous 2-d description biopolymer [2].

some properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...

Silica aerogels are nanoporous ultralight new materials with extraordinary material properties. In this study, the mechanical properties of silica aerogels, e.g. Young’s modulus, Poisson’s ratio and constitutive relation, are investigated using Molecular Dynamics (MD) simulations and theoretical analysis. In molecular dynamics simulations, an improved process of negative pressure rupturing meth...
