Elastic Properties of Model Porous Ceramics

Elastic properties of model porous ceramics ∗

The finite element method (FEM) is used to study the influence of porosity and pore shape on the elastic properties of model porous ceramics. The Young’s modulus of each model was found to be practically independent of the solid Poisson’s ratio. At a sufficiently high porosity, the Poisson’s ratio of the porous models converged to a fixed value independent of the solid Poisson’s ratio. The Youn...

Elastic Properties of substituted 45S5 Bioactive Glasses and Glass - Ceramics

CuO, Fe2O3, MnO2 and ZnO substituted 45S5 bioactive glasses were prepared. Glass derived Bioactive Glass ceramics were obtained through controlled crystallization of bioactive glasses. The formed crystalline phases in bioactive glass ceramics were identified using X ray diffraction (XRD) analysis. Density and ultrasonic wave velocities of bioactive glasses and glass ceramics were measured and u...

Mechanical properties and failure behavior of unidirectional porous ceramics.

We show that the honeycomb out-of-plane model derived by Gibson and Ashby can be applied to describe the compressive behavior of unidirectional porous materials. Ice-templating allowed us to process samples with accurate control over pore volume, size, and morphology. These samples allowed us to evaluate the effect of this microstructural variations on the compressive strength in a porosity ran...

Characterization of Elastic Properties of Porous Graphene Using an Ab Initio Study

Importance of covalent bonded two-dimensional monolayer nanostructures and also hydrocarbons is undeniably responsible for creation of new fascinating materials like polyphenylene polymer, a hydrocarbon super honeycomb network, so-called porous graphene. The mechanical properties of porous graphene such as its Young’s modulus, Poisson’s ratio and the bulk modulus as the determinative properties...
