Sodium penetration and chemically induced stresses in the hollow cylinder of Rapoport-Samoilenko apparatus – I. Constitutive modeling
(NTU "KhPI", 2007) Zolochevsky, A.; Goncharova, G.
In this paper, a comprehensive theoretical investigation has been carried out with the main focus directed at the understanding on how sodium penetration and chemical expansion in the cathode material during aluminum electrolysis affect the time dependent and chemically induced stress distribution in the hollow cylinder of the Rapoport-Samoilenko apparatus. Constitutive modeling of chemical and mechanical phenomena has been given, and the formulae of stress distribution in the cylinder of the apparatus have been obtained.
