Porous glasses with controlled porosity: Processing and modelling of mechanical properties

Porous glass specimens containing designed spheroidal porosity are used as model materials to test the prediction capability of theoretical and numerical approaches for the Young's modulus of porous materials. In particular, a finite element model called OOF, which converts a real microstructural image into a 2-D finite element mesh, has been adopted in order to assess the effect of porosity and pore structure on the Young's modulus.
