Numerical Modeling of the Porosity Influence on Strength of Structural Materials
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2019)
The effect of micro-scale structural low-level porosity on strength of structural materials was studied using the three-dimensional Unit Cell Numerical Model - UCNM. A comparison between proposed UCNM and available ...
Structure and photocatalytic properties of sintered TiO2 nanotube arrays
(ETRAN, Beograd, 2018)
One-dimensional (1D) TiO2 nanotubes perpendicular to the substrate were obtained by electrochemical oxidation of titanium foil in an acid electrolyte. In order to alter the crystallinity and the morphology of films the ...
Numerical Modeling of the Porosity Influence on the Elastic Properties of Sintered Materials
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2019)
