Influence of microstructure properties and layer thickness on strength and permeance of ceramic membranes

Abstract

We numerically predict the microstructure properties of ceramic membranes and the coupling effects of microstructure properties and layer thickness on the strength and permeance of ceramic membranes. It is found that particle size is the most important factor, followed by thickness and finally by microstructure parameters. The general design principle for strength and permeance are ht≤normalσthsKtnormalσsKs and ht≤hsKtKs respectively, with σ, h, and K the strength, thickness and permeability, while the subscript s and t represent the support and sintered layer, respectively.

Numerical analysis of mineral crystals on mechanical properties of mineralized collagen fibers

“…As a kind of biomaterials, bone has excellent mechanical properties and complex hierarchical structure. [1][2][3] Most of the mechanical loading is borne out of the bone matrix. Mineralized collagen fibers are the main bone matrix and the basis of bone hierarchical structure.…”
