Elastic properties of model porous ceramics [PDF]

Journal of the American Ceramic Society, 2000
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.
