Naomi Tsafnat, Auteur ; Guy Tsafnat, Auteur ; Allan S. Jones, Auteur |The three-dimensional microstructure of minerals and materials can be visualised in a non-destructive manner using X-ray microtomography. The digitised nature of the tomographic image allows us to generate finite element models which precisely d[...]
